User icons extending to rounded end of contact bubbles

[CTU Kyoto]

Adium bubbles have a few pixels of rounded colour at the edge where the user icon ends. I'd like to have the option to have the user icon extend all the way to the edge of the bubble. Some users might not like part of the image being cut off at the rounded edges, so I also suggest a complementary option for contact list bubbles to be square at the end the icon is being displayed.
