FlumpLibraryLoader simplification
Tesource loading: don't catch fail() on errors that are thrown from succeed()

If an error is thrown from a loader's success signal dispatch, we don't want to catch those and try to fail() the
loader that has already succeeded.
Whoops
FlumpLibraryLoader.createLibraryLoader doesn't set the loader's executor
get rid of DisplayObjectCreator, it doesn't serve a purpose
FlumpResource base class
