Extensible Weapons System

Currently both mines and front cannons are built in and fixed. It would be great to have an extensible system where weapons:

• Are loaded on startup and thus support for custom weapons from the user's Documents sub-folder.
• Can be placed on a specific location on the ship
• Can be mapped to a specific key or button.
• Support different kinds of mines ( eg. explosion, teleportation, electric shock, lose last weapon)
