Do not track external annotations
Make use of BulkFileListener to avoid processing extra files
Defer library classes check for newly created files: fixes a problem of indices not being updated at the time
Correctly check if the file is a jar file root of a library
Ther latter 2 changes fix a problem where resolve caches were not recomputed in case of deleting and readding jar files of a library
