A week worth of Mapster hacking: first, there is an experimental side view mode toggled with [F3]. Nav keys are {QWAZ}, MMB and RMB. Use with care because it is still in construction. The sector selection routines have been rewritten -- it is now possible to paste the selection into a room and a new inner loop will be added automatically (MickyC's idea). Adds m32script commands drawline16z and drawcircle16z.
