Updated importer to add SlotAbilites. Added commandlist to help command.

- Gave import an alias and a detailed help like the other commands.
- Cleaned up imports
- Added Command List for help Command
- Added static method to get Element as an index array to help import old data file
- Shuffled Extraction to the end of the StockAbilties Enum to allow easier import of SlotAbilites
- Updated importer so it imports SlotAbilites and stores them into the SQL database (Tested. Works)
- Changed to aysnc query on main thread to decrease load on server (Not sure if this works)
