git-gui: Clarify the Remote -> Delete... action

Currently, it was not really clear what all does this perform. We rename
"Delete..." to "Delete Branch..." (since this does not delete the remote
as a whole) and relabel the window from "Delete Remote Branch" to "Delete
Branch Remotely" (since the action also involves pushing the delete out).
