Rename AutoLibraryLoader (FWLite), which is misnamed

[wmtan]

The class AutoLibraryLoader, in FWLite, is badly misnamed, because, with the use of rootmap files, this class no longer loads any libraries. A new class, FWLiteEnabler, replaces AutoLibraryLoader.
The AutoLibraryLoader class is kept for now just in case any private user code is using it.
FWLiteEnabler::enable() replaces AutoLibraryLoader::enable().
Any remaining use of AutoLibraryLoader::enable() will work for now, but a warning message will be given.
