opaque clist column resizes

[<nuke bayside net>]

here's a little patch against gtkclist.c from the 1.1 branch to make
resizing the columns opaque. it really isn't suited for the tree yet,
since when you're resizing, the header buttons and most of the list items
get redrawn.. if we could work around that, it'd be pretty neat :)
