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.
Added all documentation for the onX feature and updated changelog.

Now to actually write the feature (Well, rescue it from the onX-removal tag).
BIG commit:
 * re-introduction of onMethod/onConstructor/onParam
 * tests checking error/warnings rewritten to be more heuristic, in order to accomodate difference in messaging between java6 and java 7
 * Ability to eliminate java's own output of erroneous error messages (heh); i.e. those messages that are invalidated by lombok's actions. This mechanism is used for onMethod/onConstructor/onParam
 * First steps to unifying a billion setGeneratedBy calls into a single visitor traversal for eclipse' HandleGetter/Setter/Constructor/Wither
 * To simplify 'zooming in' the tests on just a few files, added an 'accept' mechanism.
 * Updated copyright headers of website to 2013.
Bugfix for delombok mangling x++ into ++x on java7.
