Add wrappers of `evil-change' to `evil-change-commands'

[jgkamat]

I recently added a new variable to evil, evil-change-commands which allows some evil-change workarounds to be applied to evil-cp-change and similar commands.

This fixes #59.

I haven't had a chance to see if the new workarounds interfere with any evil-cp functions. I'll follow up if I find any issues (once evil get's a rebuild by tomorrow).

Please update your evil before testing this out!

See https://github.com/emacs-evil/evil/issues/916 for more information.

Fun, I've debugged this myself and arrived independently at a similar change (minus yours to evil-cp--forward-X-begin). I can confirm this PR resolves the linked issue for me.
