user-manual: mention git-gui

The git gui project seems to be still in early stages, but at a point
where it's worth mentioning as an alternative way of creating commits.

One feature of interest is the ability to manipulate individual diff
hunks.  However, people have found that feature not to be easily
discoverable from the user-interface.  Pending some ui improvements, a
parenthetical hint here may help.

(Thanks to Steffen Prohask and Junio Hamano for suggesting the
language.)

 Another technique is to use git-format-patch to create a series of
