Tons of changes, read below:
- Add special stars, the tier is not created automatically and must be
defined in its own class
	- Two new (old) stars added to this category, neutron and pulsar
	- Have the unique property of lasting (nearly) forever, but with low
	  output
	- They will explode if they ever touch one another (stack)
- Add some creative sensitivity to gravity armor so it doesn't lose
power in creative mode
- Localize. Everything. Ever.
- Improve existing localization
