Review request for GGD Tech Group.

Summary
-------

hopefully last missing situation. Variants can also have uploads, so for these the pending stuff and other covers from the base should also show, both on upload and compare.

since now current_covers can't be used as a conditional anymore give a kwargs to the template to show correct info text.

Also some other fixes, where I learned something new about python. kwargs={} is not set to {}, but to a mutable dict, so its content can stay...

Diffs
-----

/pydjango/apps/oi/views.py 1223
/pydjango/apps/oi/covers.py 1223
/pydjango/templates/oi/edit/compare_cover.html 1223

Testing
-------

it fixes some problems (the kwargs one kind of bad one), so I'll commit and put on production

Thanks,

Jochen
