Remove @Override annotation for implementing interface methods.

Mockito is configured with 1.5 source/target compatibility (according to
build.gradle). In Java 5 it's illegal to specify the @Override
annotation on method implementations based on interface. This change
removes those in order to have the Mockito compile on 1.5 without
compilation errors.

New Ant script for repackaging ASM and CGLIB from source.

This commit adds an Ant build script which pulls ASM and CGLIB source
jars from Maven central and re-packages the source code. It's not
intended to run regularly but manually. The source can then be verified
and committed to SCM.
