- Fixes to the Mac HTML5 Device selection. .app files now work correctly. - Re-enabled HTML5 in Mac Editor. - Added HTML5LaunchHelper executable to clean up the process of LaunchOn for HTML5. - Improve HTML5 SDK Settings Editor interface. Only the emscripten install directory is needed now, SDK version are automatically picked up and selected for use. - Change UnrealPak to also account for bytes saved (>64KB) and percentage size of original file (<90%) when choosing to automatically turn off compression. - Added Server Port option for HTML5 deploy to stop clashes on port 8000 - Adding more logging for use during debugging & tracing. - Added an option to turn on HTML5 tracing api and added calls to the api. - Fix up check() macros to throw alert messages and be more clear that something has gone wrong on HTML5. #codereview Ankit.Khare [CL 2452979 by James Moran in Main branch]
