Add two patches to Blackbox:

Setting _NET_NUMBER_OF_DESKTOPS may cause Blackbox to explode.  The problem
is due to a bad loop condition in Screen.cc::clientMessageEvent().  If the
difference between the new number of desktops and initial workspaceCount()
is odd, the condition is always true, or at least until "number" underflows
or overflows.  BB will usually end up munching a lot of memory and dying
when it creates thousands of desktops first, though (tracker ID 2306646).

Blackbox does not handle transparency correctly in its slit, which causes
applications like x11/bbdock to display garbled graphics.  Patch suggested
by the author of BBDock.

Port revision will be bumped separately, as there are more changes coming.
