There is a common development pattern that is not currently possible with the git plugin (as far as I can tell). I want to be able to tag a recently passed commit (with an already existing tag) and push that back to the origin repository.

So the idea being that currently my git history looks like this:

40f7af3 2012-05-17 | new commit
2738f9f 2012-05-17 | previous commit (passed)
fbafd82 2012-05-17 | older commit

When 40f7af3 gets pushed and tested, if it passes it should now get the `passed` tag.

40f7af3 2012-05-17 | new commit (passed)
2738f9f 2012-05-17 | previous commit
fbafd82 2012-05-17 | older commit

If we replace CreateTag with a ForceTag checkbox, this behavior will now be possible, as will all of the previous options with createtag.

In code, all the checkbox would have to do is enable the `-f` flag while performing the git tag command. (This is already built into the API).
