TG: Window doors are now breakable

- Window doors currently have 200 health, this can and will change if break ins
become too common.
- They still do not have wires, so you can not 'hack' them that way.
- As always, emags still hack open window doors

Changes to the hidden mining room treasures.
- Added quality pickaxes, jackhammers and drills as a possible treasure.
- - Higher quality tools are rarer of course
- - Plasma cutter is possible but rare
- Added a ripley (equipped with a drill and hydrolic clamp) as a possible
treasure.
- - There is a chance for the ripley to have a diamond drill instead of a
regular drill.

Modified the resource crate.
- - It no longer always gives you multiple stacks of every mineral.
- - It now gives you a chance to get each mineral based on rarity.
- - The size of the mineral stack is also partly based on rarity.
- - There is a very small chance to recieve nothing in this crate.
- - There is a very small chance to recieve a jetpack in this crate ontop of the
metal.
