2.7.0 Huge GUI and Message Update

I don't recommend using this build on
an production server. There could be small issues
like missing messages. If you report these issues to me
via Pm or Discord they will all be fixed on Saturday. Thanks!
Also your old language files will be copied to /Lands/Old.

If you're interested in translating Lands into your Language just grab the language files
from your /Language folder and translate them. You can send them to me and I will give you credit. Thanks.
