MAJOR FEATURES + CHANGES
==========================
Change 2828332 on 2016/01/14 by Matthew.Griffin
Ensure that warnings from Dynamic Compilation of build.cs files are propagated up to user when compiling in Visual Studio etc.
Change 2828335 on 2016/01/14 by Matthew.Griffin
Renaming AddThirdParty... functions to AddEngineThirdParty... so it's clear we're talking about third party libraries within the engine directory. This removes another couple of RunningRocket checks and uses the IsMonolithic property now.
Change 2831365 on 2016/01/16 by Ben.Marsh
Add a UAT command to remove any temp storage directories older than a specified length of time, and disable the GUBP node to do so when running with -NewEC. Better to set this up as a separate scheduled task for each temp storage folder we have, rather than run it as part of GUBP builds above a certain size.
Change 2832166 on 2016/01/18 by Ben.Marsh
Make INI file parsing much more tolerant to errors, because it prevents the build system from starting up. Now outputs warnings rather than throwing exceptions.
Change 2835725 on 2016/01/20 by Matthew.Griffin
Removed more uses of RunningRocket functions
Switch Linux staging check to see if required files exist until switched to using receipts
Always stage CrashReporter for Linux
Mac and Linux will not use Compile Lean And Mean when generating project files
Allow normal DynamicCompilation check to occur in binary builds
Allow XMPP dependency on WebRTC now that it's publically distributed
Change 2835864 on 2016/01/20 by Matthew.Griffin
Made sure -rocket is passed when generating project files as this has to work from UnrealVersionSelector with every version of the Engine we've released.
Also tidied up some arguments that are set in UVS and never used.
Change 2839932 on 2016/01/22 by Matthew.Griffin
Removed last uses of RunningRocket from UnrealBuildTool
Changed Mac Build.sh so that it doesn't try to build UBT so that it can be used in installed builds the same way as windows.
Combined code doing very similar things for single games and rocket projects.
Removed check on whether to add client and server targets in Rocket as we don't distribute the .target.cs files.
Removed RunningRocket function and the code checking for -rocket on the command line
Change 2846971 on 2016/01/28 by Matthew.Griffin
Replaced RunningRocket with IsEngineInstalled for all Engine programs that won't need to be built.
Change 2853879 on 2016/02/03 by Matthew.Griffin
Added UnrealLightmass to list of programs to build when Build Solution is used and Editor configuration is selected

[CL 2854567 by Ben Marsh in Main branch]
Whenever a blank engine association is read from a .uproject via GetEngineIdentifierForProject(), it checks up the directory hierarchy for an engine capable of loading it via its .uprojectdirs search directories. If found, it will use that engine's local identifier from the registry, or register it if it doesn't exist.
Setting a project's engine association to an engine which is capable of loading it via it's .uprojectdirs will cause it to write a blank engine association string into the .uproject (and triggering the behaviour above on open).

* Lots of code moved into IDesktopPlatform for sharing with Launcher and Mac (including setting up file associations, querying project versions, etc...)
* Hack to enumerate all the known launcher engine installations. Does not use registry keys any more. Will probably change to use a list of installations generated by the launcher at some point soon.
* List of registered GitHub builds is stored in HKEY_CURRENT_USER
* Switching engine versions is now done through a dialog rather than through the context menu.
* VersionSelector includes a version number for shell integration, allowing it to defer to an existing installation of the same version if necessary.
