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)

Rob asked me to back out GENERATED_*_BODY -> GENERATED_BODY change for now until the "_Validate and _Implementation auto-generation" discussion is over.

#ttp 330039 EDITOR: Platform-agnostic editor code depends on Windows-only VSAccessor headers
#detail Source code access is now extensible via plugins, so any new editors can be easily added.
#add Added SourceCodeAccess module that routes access via plugins.
#change Moved much of the old VSAccessor code into a new VisualStudioSourceCodeAccess plugin.
#add Added a counterpart XCode plugin & migrated the code from FSourceCodeNavigation (Applescript etc.) into there.
#remove Removed applescript for XCode access (it is now done via code).
#remove Removed source code access functionality from platform layer.
#add Added details customization for source code access settings, so users can choose their own accessor.
#remove Removed dependencies on VSAccessor.
#change Changed API in SWidget to not require building a string to be parsed, instead this acesses and forwards filenames & line numbers.
#extra Tested on Mac by Mark S.
