Database Upgrading system

[MrOinky]

A system that "upgrades" databases when there are changes to its structure for hopefully obvious reasons

TODO:

• Upgrade File Structure
• Upgrade Check
• Table Operations (rename, move, delete, etc.)
• Upgrader (the thing that actually runs through the things to do

Extras (may be added later):

• Custom alterations (being able to run a list of operations on the fly)
