UE-7184 - Show game c++ classes and engine c++ classes in the content browser
The Content Browser now has extra entries for "Game C++ Classes" and "Engine C++ Classes" (with "Game" and "Engine" being renamed to "Game Content" and "Engine Content" respectively). These new folders serve as hosts for the list of available C++ modules, with each module internally mirroring the folder structure on disk.
For example:
- Game C++ Classes
- ShooterGame
- Classes
- Bots
- ShooterBot
- ShooterAIController
- [...]
- [...]
The Content Browser allows you to navigate and search these classes like you can with assets, and provides convenient access to either edit an existing class, or create a new class (either within a selected folder, or derived from a selected class).
As the Content Browser only shows you known UClass types, any new classes need to be compiled into a loaded module before they will appear. This means that adding a new class will now automatically hot-reload your target module. Should you prefer to handle building and loading your modules manually, you can disable the automatic hot-reload via "Editor Settings" -> "Miscellaneous" -> "Hot Reload" -> "Automatically Hot Reload New Classes" (see UEditorUserSettings::bAutomaticallyHotReloadNewClasses).

Other Updates:
- The WidgetReflector is now in its own module as well. It will be converted to a plug-in later.
- The Public API of both Slate and SlateCore has largely been reorganized for better discoverabilty. More cleanup work is needed.
- Added a lot of missing API documentation and fixed existing ones. More and better documentation is needed.
- Removed dead code, fixed a couple things I stubled upon, and conformed to coding guidelines (NULL vs nullptr, line breaks, etc.)
Upgrade Notes:
- The Slate Remote Server is currently disabled - will be re-enabled shortly!
- If your module previously had a module dependency to 'Slate', it now also needs a PrivateModuleDependency to 'SlateCore' in its Build.cs file.
- If your module exposes in any of its Public header files types that are now declared in SlateCore, it needs a PublicModuleDependency to 'SlateCore'
- The ToolTip property type on SWidget has changed from SToolTip to IToolTip; change local variables to TSharedPtr<IToolTip> instead of TSharedPtr<SToolTip> where needed
- IToolTip is not a widget. If you need access to the actual widget that represents the tool tip, use IToolTip::AsWidget(); If you need access to the tool tip's content, use IToolTip::GetContentWidget()
Troubleshooting:
- After syncing to this changelist you may have to clean your /Engine/Intermediate/Build/ directory and rebuild your entire project
- If in your project you are getting linker errors for unresolved types that are now declared in SlateCore, you may be missing a dependency to 'SlateCore'
- If in the Engine code you are getting linker errors for unresolved types that are now declared in SlateCore, you may need to rebuild the entire Engine
