update support model after rotate, swap and flip

* a worker thread puts every new task into a "pending" queue immediately after accepting it
* the "pending" check is checked regularly for old items -> they are reinjected into the task queue
* the risk of losing a task is now close to zero


git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@949 bbaffbd6-741e-11dd-a85d-61de82d9cad9

improved performance of "update_progress_bar" slightly

An attempt to get the resolution for each axis to be controlled individually.  Now all axes properly named and working just fine...  changed the default to 0.0001 for now untill gcode resolution selection is available.

An attempt to get the resolution for each axis to be controlled individually.  However not implemented properly yet so all axes still key off the x-axis resolution.
