* Shared PCHs were disabled for static libraries in monolithic builds -> now disabled for static libraries in all builds
* Modules could not use their own shared PCH in non-monolithic builds due to exports -> now disabled if their binary has exports

Changed Module Manager so that it adds restricted directories to modified PATH if they exist, removed unnecessary recursive use of FindModulePathsInDirectory

* Import libraries are added to the build manifest whenever precompiling modules
* UHT now just generates headers to the project directory, and headers aren't included in the engine distribution. UHT was generating them anyway, just not writing them.
* Plugins binaries now just use UE4Game prefix in Rocket (since that's where they're built from), rather than using a special name.
* Platform-specific plugins are not explicitly excluded from builds - will be stripped out by directory instead
* XMPP is not manually excluded from Rocket builds.
* Removed BuildingRocket() function.
