Kiauto

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.

Added
- More support for docker environment in the pcbnew scripts

Changed
- Now eeschema_do reports ERC warnings as warning messages

Added
- Support missing *-lib-table in user config
- Create the KiCad config dir if it doesn't exist

Fixed
- Two missing dependences.

Changed
- Debug and info colors.
