gui: Added a method that removes all streams from the view used in the acquisistion window, so no PyDeadObjectErrors occur after it's destroyed.
gui: created an ignore_dead decorator which is used to ignore PyDeadObjectError in the gui.canvas module, which can occur because delayed calls might try to access objects that get destroyed.
gui: Sublime Text 2 was pretty helpful in removing trailing spaces. Thanks ST2!
andorcam2: read the install path of andor sdk from the /etc directory

fixes a bug preventing to load libandor if it was not installed in the default path
andorcam2: whitespace clean up from Eclipse
driver: improve test of simulated stage and combinedactuator

fix some bugs in combinedactuator
driver: combinedactuator combines axes in moves, if they are from same child

Small improvement to all the child handle multiple axes move (maybe more efficiently)

Also remove ArgumentError, and use ValueError, more pythonic
pigcs: improve move with C867

correctly stop the move if requested (need to force SMO to 0V)
long moves don't work
set correct min speed to avoid unexpected fast speed

don't wait too long if the move has finished earlier
