* Fix issue handling symbols with multiple inheritance.
* Remove unused code from the symbol library manager object.

When editing or viewing library symbols, the files are watched for
underlying changes. If any occur, the user is either prompted to reload

silently updated to the current version on disk.

recieving invalid SAMBA packets and turns off assertions entirely when
running in release (non-debug) mode
