an unimplemented, unused function declaration in DSNLEXER.
 
Improve the output formatting of THROW_PARSE_ERROR().

in *.kicad_pcb file loading times.

Replace in EDA_TEXT::Draw the parameter EDA_DRAW_PANEL* aPanel  by EDA_RECT* aClipBox, which is the actual parameter used by Draw.

Eeschema: Add dialog and utilities (help files ...) to create BOMs from generic netlist, using python scripts or xsltproc+style sheet.

Rename witha  more explicit name bom-example?.py , fix some issues and move them from script/bom-in-python/ky to script/bom-in-python
Rename ki.py utility to more explicit  ky_generic_netlist_reader.py

* Do not search for footprint when no footprint is defined for a component
  in the netlist.

Rename invoke_a_dialog.h.  Code an alternate implementation for std::string BOARD_ITEM::FormatInternalUnits( int aValue ), for verification.
