Option for formatting local chat, formatted all code to Java 7

This plugin almost fit my needs, I made a few small additions that others may find useful.
- Added a config option to format local chat.  This should be used with cancel chat events on, and it will format your text from the proxy.
- Formatted all of the code to Java 7 standard (sorry, it really annoys me)

Feel free to accept, decline, or make changes to this, I think it would be a nice addition to the plugin.

Edit: Coding error, fixed is second commit
