CEO-187: Don't force equals definitions

This is an identical set of changes that were already merged into the master branch of equalsverifier in the main repo.  The difference here is that the changes are applied to a branch based on the 1.4.1 tag.

The official release which includes these changes (1.5) also includes incompatible upgrades for cglib and asm.  So, I've applied these changes to the version we currently use.
