[PATCH v2 2/4] git-gui: Add option to disable the revert confirmation prompt

[Pratyush Yadav <me@yadavpratyush.com>]

When reverting files (or hunks or lines that future commits will add), a
confirmation dialog is shown to make sure the user actually wanted to
revert, and did not accidentally click revert.

But for some people's workflow this is an hindrance. So add an option to
disable this behaviour for people who are comfortable risking accidental
reverts.

The default behaviour is to ask for confirmation.
