1) Changed the pre/post compile notifications from module notifications to process commands.
2) Added server command to notify that we want re-instance patching (two phase)
3) Added support for two phase patching to enable re-instancing without all the limitations.
4) Added a null CDO check for old blueprint classes (approved by Phillip)

LIMITATIONS:
1) Re-instancing will only update UClass instance data.
2) Adding and removing properties should only be done towards the end of a class or structure and can not be followed by complex data types.
3) Adding and removing properties from a base class should not be done if a derived class contains complex data types.
KNOWN ISSUES:
1) Changes to enumerations and structures will not be reflected in existing blueprints. However, adding new nodes to the blueprint will show the updated enumeration or structure.
2) If a class contains an enumeration or structure as a member, the class will not be re-instanced if enumeration or structure is changed.
CHANGES:
1) LiveCodingServer
1a) Modified to always execute certain static instances during load.
1b) Modified to exclude the _Statics static structures to avoid patching to old copies.
2) Added support for LiveCoding reinstancing
2a) Refactored deferred registration system for UClass, UEnum, and UScriptStruct to use a common system that works for normal game, hot reload and live coding.
2b) Type specific version check data is possible (i.e. enum doesn't have a size)
2c) Single registration static for UClass
2d) Single registration class for all types that is just a blind forward to API.
2e) Static and dynamic registrations use different API entry points to avoid having overloaded argument lists that just apply to one or the other.
2f) Shims for older API
3) New common "Reload" system to avoid using HotReload code.
3a) Support common delegates regardless of who is reloading/reinstancing.
3b) Re-instancing code moved from HotReload to Kismet2 (where the bulk of the re-instance code already existed).
3c) Modified PyWrapper to use new helper class instead of depending on HotRelaod
3d) Added WITH_RELOAD which is defined if HotReload or LiveCoding is enabled.
3e) Modifed existing code to use new #define and delegates.
Robert did the review on the changes covered by Part 2. Remaining changes are all straightforward.

* Removed code to invalidate makefiles when adding new source files. UBT should be reliable enough to make this determination itself nowadays, and ignored -invalidatemakefilesonly argument was causing modules to be recompiled.
* Fixed incorrect config section name when determining whether to allow hot reload from IDE. Now prevents hot reload from IDE when live coding is enabled.
* Added error message when trying to add a new class with Live Coding enabled.
* Added error messages when trying to start Live Coding after a hot reload has taken place.
* Added error messages when trying to hot reload with Live Coding enabled.

* Compile dropdown now just contains a checkbox for enabling live coding.
* Compile dropdown has a link to open the editor preferences window.
* Live coding can be enabled from the editor settings window.
* Option to show the console on startup is now folded into the startup mode.
* Options in the editor settings window are greyed out unless live coding is enabled.

Allows fast iteration of C++ changes without restarting the application. To use, select the "Live Coding (Experimental)" mode from the drop down menu next to the editor's compile button, or type "LiveCoding" into the console for a monolithic build. Press Ctrl+Alt+F11 to find changes and compile.
Changes vs standalone Live++ version:
* UBT is used to execute builds. This allows standard UE4 adaptive unity mode, allows us to reuse object files when we do regular builds, supports using any build executor allowed by UBT (XGE, SNDBS, etc..).
* Adding new source files is supported.
* Custom visualizer for FNames is supported via a weakly linked symbol in a static library (Engine/Extras/NatvisHelpers).
* Settings are exposed in the editor's project settings dialog.
* Standalone application has been rewritten as a Slate app ("LiveCodingConsole"). There is an additional option to start the program as hidden, where it will not be visible until Ctrl+Alt+F11 is hit. Similarly, closing the window will hide it instead of closing the application.
* Does not require a standalone licensed version of Live++.
Known issues:
* Does not currently support class layout changes / object reinstancing
