[PATCH 4/4] git-gui: allow Ctrl+T to toggle multiple paths

[Johannes Schindelin <johannes.schindelin@gmx.de>]

It is possible to select multiple files in the "Unstaged Changes" and
the "Staged Changes" lists. But when hitting Ctrl+T, surprisingly only
one entry is handled, not all selected ones.

Let's just use the same code path as for the "Stage To Commit" and the
"Unstage From Commit" menu items.

This fixes https://github.com/git-for-windows/git/issues/1012
