A little housekeeping

I haven't added any features or anything, but, like the title says, a little housekeeping. The most important change is probably that it works again. Before, for some reason, it was having trouble finding players. There was something wrong with the case sensitivity. The second most important change was that I removed the vault dependency. It existed only for permissions checking, which is built straight into bukkit. The third change was that I changed the color character from the wierd 8 thing (no such button on my keyboard) to '&'. This stops bukkit from complaining about file encoding issues, and it is probably a little easier on the users as well.
