Made table information available to scripts (#49)

- Added a property with table information to session and result set Script types
- Added the ability to add new key bindings to the script
- Rebuilt the foreground job dispatcher to reduce the occurrence of the progress indicator showing up when no job was running.
- Fixed rebinding of keys. Rebinding a key will no longer clear other keys for the old or new bindings.
