v0.8.0

Added

• The KiBoM and internal BoM generators now support configuring the
  separator used for the list of references.
• Help for filters and variants.
• Support for new pcbnew_do export options.
• Filters for KiBot warnings.
• Columns in position files can be selected, renamed and sorted as you
  like.

Fixed

• KiBom variants when using multiple variants and a component uses more
  than one, specifying opposite rules.
• Problems when using the pdf_pcb_print output and variants to remove
  a component with ridiculous pads that only has solder paste (no
  copper, nor even solder mask aperture).
• Excellon drill output when using unified output and not using default
  KiCad names.
