[PATCH] show signature of commit in gitk

[Daniel Fahlke <flyingmana@cotya.com>]

but still depending on the added --show-signature as argument

longer explanation:
git supports for some time now signed commits, and also show the
signature and its trust level inside the `git log` command.
Now, it can also get shown in gitk.
