Kiauto

Added
- --fill_zones/-f option to 'pcbnew_do export' to fill zones before printing.

Changed
- Filtered errors are displayed as warnings, but ignored.
- Filtered warnings are displayed as information.
- When an error/warning is filtered a debug message informs which regex matched.

Added
- --errors_filter/-f option to provide a file containing errors to ignore from DRC/ERC.

Fixed
- Sometimes when using a WM the "pcbnew_do export" failed to open the Printer dialog.
- Sometimes when exiting xdotool didn't find any window and reported error.
- When the filled zones changed during DRC the PCB could be saved even when we didn't
specify --save

Fixed
- Under some situations the EEschema plot dialog failed to clear the old file path
and we pasted concatenated. Was introduced when fixing the browse button selected.

Added
- --wait_key/-w option to send the commands step by step (debug)
- --start_x11vnc/-s option to start a server so we can monitor what's going on (debug)
- --use_wm/-m option to start a window manager (fluxbox) so we can interact better (debug)

Changed
- Now we exit eeschema and pcbnew without killing the application.
- Default record height now is 960.

Fixed
- Error and Warning dialog detection. Now we use more specific regular expressions.
- Sometimes the 'Plot Schematic Options' starts with the browse button selected and we
must move left.
- Sometimes the netlist dialog starts with the generation button selected and we move to
the plugin button instead. Now we detect it and go back to the generate button.

Added
- Support for PS, DXF and HPGL to the schematic export.
- Support for eeschema already running.
- Support for loading KiCad 4 schematics (asking for Remap symbols)

Changed
- pcbnew_print_layers to "pcbnew_do export" to be coherent with "eeschema_do"
- pcbnew_run_drc to "pcbnew_do run_drc" ditto

Fixed
- --ignore_unconnected of pcbnew_run_drc wasn't implemented.
- ERC omitted warnings if errors were detected.
- The project file could be altered, or even lost, during schematic export.

Changed
- Now we use setxkbmap instead of xset to test X is working.
If setxkbmap isn't available we default to xset.
