Lots of fiddling

+Use JavaPlugin's inbuilt yaml configuration
+Customize message color stripping
+Change connection status on connect failure
+Add potential for passwords that aren't the username
+updated plugin.yml
-Prefs system (redundant)
-Color hash (That's not how chat colors work, remember our testing
period? ChatColor.COLOR_NAME or nothing)
-Removed unused class + imports
-Removed Ted's school's IP.

TODO
+Use password (wasn't sure which short and char to change, didn't check)
+Reintroduce server hash color? Maybe as a config option.
+/exchat mute <servername> <username> or /exchat mute <loginname>
