v1.2.0

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.
