Rewrote ui-validate to have support for ui-validate-watch

The tests have not been updated yet to reflect the new syntax
Updated syntax on old specs and stubbed new ones

I'm starting to wonder if perhaps we should make uiValidateWatch a separate directive with lower priority?
Fixed uiValidateWatch

For some reason I can't checkout this branch locally.

Everything seems to work now, just need unit tests and peer review.

This has a breaking API change, you now must wrap expressions in strings.
This is to allow 2-step parsing. Once for the object of validators, and again to validate.
