BPython:

-- fixing a last minute bug: scripts w/o guis that called the file selector were
   not being checked for errors, which could cause crash dumps upon exiting.
-- docs: updates for Draw (fixed example) and Material (added tex related methods docs)

Scripts:
-- added some more scripts, all I could get in shape in time (at least they export / import back).
   Only tested on linux.
