- fixed the Tcl Command AlignDrillGrid
- fixed the Tcl COmmand Panelize, Excellon panelization section
- Fixed an issue in Tool Calibration export_excellon method call
- PEP8 corrections all over the app
- in camlib.py, CNCJob class -> generate_from_excellon_by_tool() was
failing in the line to sort the tools due of been unable to compare
between dict's. I replaced that section.
