git-gui: allow Ctrl+T to toggle multiple paths

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.
