This release makes use of a brand new injector: LightInjector.
This change will reduce the burden of maintaining and updating the API to new mc versions.

The API itself has not changed, so updating to this version should be as easy as replacing the old jar with the new one.
Note, however, that some login packets will not be intercepted anymore starting from this version (game packets are not affected). See the LightInjector javadoc for more information.
