A few more changes. Makes bluespace ore satchel better.

- Makes the mining satchel pick stuff up a bit differently.
- Adds a failsafe for mining satchels so you can't pick up too many items at once. (set to 100)
- Makes the bluespace ore satchel ACTUALLY bluespace.
- Adds 'current capacity' so ore satchels and mining drills can only hold a certain amount.
