Fix #77 - Fish get captured when saving objects near water.
Remove some unecessary fields from the grabber/mapper. Fix #77 again (for realz).
Add support for overriding preserving the original orientation. When pasting in a new position, follow the ground instead of preserving old orientation.
Forgot to remove test code.
Some tweaking and cleanup in the save/load code. Doesn't behave nicely with stacked things still.
