Newly installed versions of the engine will now attempt to copy the project-agnostic config settings from a previous engine installation. This happens by way of a versioned manifest that copies old versions when the manifest does not exist, or is a different version. This code path is benign for non-installed versions of the engine (or FPaths::ShouldSaveToUserDir() is false).
EditorGameAgnosticSettings and EditorUserSettings ini paths have been renamed to EditorSettings and EditorPerProjectUserSettings respectively to better convey their purpose. In general, most settings should be saved in EditorSettings (project-agnostic) so that they apply regardless of which project is open. We have some way to go migrating existing settings for this to be the case, however.
Some previously per-project configuration files are now project-agnostic (such as Editor.ini, EditorKeyBindings.ini, and EditorLayout.ini)
GEditor->Access...Settings and GEditor->Get...Settings have been removed in favor of direct access of the CDO through GetMutableDefault<> and GetDefault<> respectively. Global config ini filenames that are not set up are now neither loaded nor saved on build machines, to handle the problem of indeterminate state more generically.
This addresses UETOOL-270 (Most editor preferences should be project-agnostic)

- Incorporates PR #934 (fix a broken path to RunXBuild.sh when building UBT for Linux) contributed by amigo (3dluvr).
- Moved more code out of #ifdef-s to make compiler see it when compiling on all platforms.

Slate Widget was failing, because of missing Slate dependencies. Testing introduced a couple of problems which all was fixed by this CL:
1. I introduced AdditionalDependencies in .uproject file and change "Add Code To Project..." procedure to fill this array if needed. UBT reads this field and builds the project with required modules. Needed for Slate classes.
2. Changed UHT to #include missing headers in generated.h files if it was missing an include for it's super class. It was causing problems if we were trying to add a subclass of BrushShape -- BrushShape.h didn't have #include "Brush.h" and UBrushShape was inheriting from UBrush.
3. Above problems also occured for Slate classes, but not all of them was UCLASSes, so I had to fixed that manually.
4. "Add Code To Project..." functionality was not invalidating UBT makefiles, which lead to omitting new source files during hot-reloading (even thought it was reporting a success). This change also should improve a bit performance, cause right now there is no "gathering" step -- there is only invalidate step which is a lot quicker.
5. Fixed "Selected Class Source" link to source class in Slate Widget and Slate Widget Style class.

We already had FPlatformProcess::CreateProc/CloseProc pair (which is part of larger set with WaitForProc(), TerminateProc(), GetProcReturnCode(), etc). FProcHandle::Close() made the API more confusing (and actually introduced bugs, because it did not call CloseProc() until recently).

- 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.

This is needed for UBT to update its makefiles when we add new code via the editor.
Updating UBT makefiles is more typically handled by re-generating project files, however on Windows we use DTE to inject new files directly into Visual Studio in an attempt to avoid re-generating project files (as it produces modal popups that block operations), so we need to perform a gather instead so that UBT knows things have changed.

* Only try to build UBT if it's not present in the *target* engine directory (as opposed to the running engine directory). Fixes problems with running from launcher installation.
* Fix building UBT from paths that contain spaces.
* Better logging of what's going on when trying to build UBT (and possible failure points)
* Remove duplicate entries in installation list, and make sure that every path is stored in the same way. Was allowing a number of paths to contain relative portions.
