[PATCH] gitk: Display the date of a tag in a human friendly way.

[Anand Kumria <wildfire@progsoc.org>]

By selecting a tag within gitk you can display information about it.
This information is output by using the command

 'git cat-file tag <tagid>'

This outputs the *raw* information from the tag, amongst which is the
time - in seconds since the epoch. As useful as that value is, I find it
a lot easier to read and process time which it is something like:

 "Mon Dec 31 14:26:11 2012 -0800"

This change will modify the display of tags in gitk like so:
