Updated the javadoc of each and every feature annotation that lombok has:
* Removed most documentation and instead put in a link to the much more up to date and extensive documentation at http://projectlombok.org/features
* Getting ahead of ourselves a little, added notes on onConstructor/onParam/onMethod which we are about to add in the next few commits.
* Updated copyrights to 2012.
