d1fdbadd19 Multiprocessing updates / fixes:
- ForkedProcess is much more careful with inherited state -- closes file handles, removes atexit and excepthook callbacks
   - Remote processes copy sys.path from parent
   - Parallelizer has ProgressDialog support
   - Many docstring updates
   - Added some test code for remote GraphicsView rendering

72006fe05b Added custom multiprocessing module:
- allows starting new processes and controlling them remotely from the parent process
  - remote processes can run their own GUI, Qt signals can be connected between processes
    (in general this is not possible with the built-in multiprocessing module due to
    the use of fork() ).
  - Control works by a system of proxy-objects such that controlling a remote process
    looks almost exactly like working with local objects.
  - Uses sockets to communicate between processes (so in theory could be made to 
    work over a network), but also includes a mode that uses fork() to allow fast
    parallelization.
  - Wicked-easy inline parallelization by adding only one line of code to break up work between
    processes (requires fork; sorry windows users)
