v1.2.1 - Update Checking

Now the plugin will annoy you when there's updates to be had! Wooo! Except it doesn't look at GitHub releases quite yet... maybe something to consider for the future.

• Nametag Maker now checks for updates on the spigot page whenever someone logs in with the permission nametagmaker.update.
• Fixed an issue where /nametag refresh was not showing up under help.
