[PATCH] gitk: use single blamestuff for all show_line_source{} calls

[Max Kirillov <max@max630.net>]

There seems to be no point to search for several origins at once.
I doubt it is even fully working (because there is one blameinst),
but blamestuff for some reason is an array. Also, it is not cleaned
after blame is completed
