Change 2799478 on 2015/12/11 by Robert.Manuszewski@Robert.Manuszewski_NCL_Stream1

Change 2789867 on 2015/12/04 by Robert.Manuszewski@Robert.Manuszewski_NCL_Stream1
UnrealHeaderTool plugins no longer need to be a separate plugin and don't require UnrealHeaderTool source code changes to work.
- Merged ScriptGeneratorPlugin with ScriptPlugin
- Introduced the concept of UHT plugin support for plugins so that UHT's source files don't need to be modified to make it work with external plugins
- Added RuntimeNoProgram module type (module that can be used at runtime but not by program targets).
- Fixed logic with project file path setting in the engine. It will no longer try to crate a full path from an already rooted path.

TEnumRange - enabled ranged-based for iteration over enum values.

MAJOR FEATURES + CHANGES
==========================
Change 2783106 on 2015/11/30 by Robert.Manuszewski@Robert.Manuszewski_NCL_Stream2
Introduced GC UObject clusters. GC clusters provide means to create disregard for GC subsets at load time (e.g. Materials with material expressions and their textures).
- Saves about 25ms in reachability analysis (58ms -> 33ms)
- UObject classes/instances can now be marked as cluster root objects with CanBeClusterRoot() function override.
- Cluster creation is automatic. Clusters don't require any manual handling for GC to collect them when nothing is referencing them.
- Moved token stream processing to a new class FFastReferenceFinder to make it more generic and re-usable by other code
- Removed REFERENCE_INFO macro from GC code and replaced it with a local variable (saves about ~1.9ms: 33.2ms -> 31.3ms)
Change 2773094 on 2015/11/19 by Steve.Robb@Dev-Core
Multicast script delegate check for existing bindings replaced with ensure.
Multicast native delegate no longer checks for existing bindings.
Removal of old delegate code.
Some FORCEINLINEing to improve debugging experience of stepping into delegate code.
Change 2782180 on 2015/11/27 by Graeme.Thornton@GThornton_DesktopMaster
Make scoped seconds timer class available outside of stats build. Normal usage macros still remain guarded
Added SCOPE_SECONDS_COUNTER_RECURSION_SAFE which only times during the outmost instance of a recursive function
Added SCOPE_SECONDS_COUNTER_RECURSION_SAFE_BASE and SCOPE_SECONDS_COUNTER_BASE which are defined in all build types, for easy temporary timing in Test/Shipping builds.
Added a boolean parameter to the timer class which can be used to disable it without having to mess around with scoping the calling code
Change 2782635 on 2015/11/30 by Graeme.Thornton@GThornton_DesktopMaster
Added GetTimeStampPair() to the filemanager and platformfile interfaces. Requests timestamps for a pair of files where we assume that both files would always exist at the same wrapper level. Allows us to skip file system queries for localization package lookups where the native file is in a pak but the localized file doesn't exist.
Change 2775153 on 2015/11/20 by Jaroslaw.Surowiec@Stream.1.JarekSurowiec

New TryGetBoundFunctionName() to aid the debugging of delegate bindings in non-shipping configs.
Change 2773114 on 2015/11/19 by Steve.Robb@Dev-Core
FMath::IsPowerOfTwo is now templated to take any type.
Change 2773643 on 2015/11/19 by Steve.Robb@Dev-Core
GetDelegateInstance() calls replaced - delegate instances never compare equal unless you are comparing two unbound delegates (both null) or comparing a delegate with itself.
Change 2777686 on 2015/11/23 by Steve.Robb@Dev-Core
GitHub #1793 - File write flags argument
Change 2780590 on 2015/11/25 by Steve.Robb@Dev-Core

Change 2780962 on 2015/11/25 by Jaroslaw.Surowiec@Stream.1.JarekSurowiec
Stats - Added FStatsWriteStream for basic saving stat messages into a stream, initial support for reading a regular stats file, minor performance optimization, coding standard fixes
#jira UECORE-170 - Improve profiler loading performance (wip)
Change 2781887 on 2015/11/26 by Jaroslaw.Surowiec@Stream.1.JarekSurowiec
Profiler/ProfilerClient - Removed unneeded synchronization points, replaces with task graph SendTo jobs, removed PROFILER_THREADED_LOAD, replaced with new stats loading mechanism, should be around 2x times faster (4x since the optimization pass)

Change 2781893 on 2015/11/26 by Steve.Robb@Dev-Core

#jira UECORE-170 - Improve profiler loading performance (wip)

#UE4 Removed DiskCachedAssetDataBuffer as it was not strictly necessary and was triggering a crash when loading the cached registry from disk. This data is now stored directly in DiskCachedAssetDataMap. It was already true that this map does not change outside of SerializeCache but now it is critical since NewCachedAssetDataMap keeps pointers directly to its values.
Asset registry fixes by Bob Tellez. Possible fix for UE-23783.
Change 2782564 on 2015/11/30 by Robert.Manuszewski@Robert.Manuszewski_NCL_Stream1
FReferenceCollector::AddReferenceObjects performance improvements for TArrays. ARO will no longer call HandleObjectReference multiple times but instead will call HandleObjectReferences just once (currently only implemented for FGCCollector). Reduces the number of virtual function calls while GC'ing.
Change 2782716 on 2015/11/30 by Steve.Robb@Dev-Core
UObject serial number array initialized for debug visualization.
Change 2782933 on 2015/11/30 by Steve.Robb@Dev-Core
