2.0-RC2

This is a release candidate. I plan to wait for next Ubuntu LTS release before production release (which should be in a few days). In the mean time, I plan to deploy it to few machines and test it a bit more.

Changelog:

• local cache of .sql file contents (and thus added temppath mount option)
• added support for reporting exact file sizes (which is also why we need local cache)
• added support for triggers
• added support for os authentication and bequeath connections
• all source is obtained from all_% views, no more reliance on dbms_metadata (which was too slow)
• added support for editionable keyword
• fixed a few bugs
