3475: Make the format/layout used in _extract_commit_message() customizable

What version are you running?
RBTools 0.6.2

Describe the enhancement and the motivation for it.
Where I work, we've generally standardized on having a 'Review: <url>' line in our commit messages instead of 'Reviewed at <url>' which is provided by 'rbt patch -c'.
A nice feature would be making the format/layout customizable.

What operating system are you using? What browser?
Windows 8.1 and Firefox 30.
