BPackageManager: Support installing/updating local package files

* The Install() and Update() versions that take a const char* array
  now check whether a string looks like a path to a local package file.
  If so, they use that file instead of interpreting the string as a
  search string.
* Extend the repository hierarchy. There's now a LocalRepository base
  class from which InstalledRepository and the new MiscLocalRepository
  derive. The latter is instantiated once and collects all package files
  specified by path.
