[PATCH v2 1/4] 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.
Probably is is not 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.
