Removal of manager().getMinecraft()
Removed License note
Made PresenceFootsteps "run" on 1.7.2:

- Not working fully yet
- Primitive support is temp-disabled because of obf names screwing things up
- Uses the official Resource Pack Repository instead: Uses ONE PF-Compatible pack as the current pack (didn't figure yet if it's the topmost or the bottommost, should be the topmost=tail of the internal structure)
- Converted blockIDs to Strings: Blockmap not updated yet
- For technical reasons, the domain:location delimiter for block names is a ">" instead of a ":", because ":" is recognized as a delimiter in the Properties so I don't want to deal with that issue yet.
