Version 0.7

Changes contained in changelog. In essence:

- Added per-gate permission. Permission to use the gate is konseptgate.gate.<gatename> . Command to toggle permission per-gate is /kg toggleperm <gatename>
- Fixed issues to do with /kg list with no additional parameters not looking nice
- Apologies, contains a duplicated fix from my previous pull request, about the NPE with insufficient arguments.

Let me know if there's anything else you want doing :)
