[Foldit] Fix attachement panel movement
The layout for the Small molecule panel's fragment attachment placement subpanel had a bug where trying to move it resulted in it jumping all over the screen.
This cleans up the associated code, as well as making the movement more sane.
Unfortunately, the easy way to do this was to make the attachment panel separate, such that it now no longer moves with the Small Molecule Design panel. This is probably fine, as the attachement panel's life is short anyway, so the fact it's not coordinated is not too big a deal.
RELEASE NOTES: Fix movement behavior of the Small Molecule Design's Attachement panel.
