changed the gcode exporter code to allow a specific definition of the safety height (instead of previous "max(safetyheight, homeheight, startz)")
moved "startz" offset (based on the configured measurement unit) from SimpleGCodeExporter to the Gui code to allow more control
slight beautification of the gcode exporter code (added spaces between operators and after commas - according to PEP 8)

git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@157 bbaffbd6-741e-11dd-a85d-61de82d9cad9

 make sure that the path generators never get stuck in in infinite loop caused by floating point inaccuracies
 define a maximum recursion depth (20) for the PushCutter algorithm (i.e. maximum precision = 1/(1^20) of bounding box width)


git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@156 bbaffbd6-741e-11dd-a85d-61de82d9cad9

 fixed a small nasty bug, that occours in the DropCutter for small values of "material allowance"
 
 Description: ODE did not take the "extended" drill shapes into account, when deciding, if
 collisions are possible. Thus the collide callback was never called.


git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@155 bbaffbd6-741e-11dd-a85d-61de82d9cad9

 use a calculated "safe height" instead of "utils.INIFINITE" for a boundary limit failure in DropCutter (otherwise it looks like a bug)
  - issue a warning once

 derive the ToroidalCutter shape from the CylindricalCutter (not perfect, but it works)
 prevent all impossible combinations of tool and path settings by disabling the respective controls
