1. Added new mines to rank association. To use it, create your ranks and mines as you would normally and type in /mines addrank <mine> <rank>. You may add multiple ranks if you wish. Now only the people in the ranks added to the mine can break blocks in it. Remove ranks by typing /mines removerank <mine> <rank>.
2. Fixed some error messages. Grammar is important.
3. Other minor bugfixes that aren't worth mentioning here.
