I thought of a better way to handle design rule files (herein referred
to DRFs).  Either add LoadDesignRules() and SaveDesignRules() to the
PLUGIN object (which really needs to be renamed PCB_PLUGIN now that we
also have SCH_PLUGIN) or create a separate DRF_PLUGIN.  My preference is
the former.  Both of these methods would be implemented for kicad board
files which would be useful for saving design rules in the kicad_pcb
file itself and exporting them to a stand alone file which could be
imported into another board design.  For third party plugins, only DRF
loading would be provided for apps (such as eagle) that save their
design rules in a separate file.  One thing that would make doing this
somewhat easier is if we had a DESIGN_RULE_MANAGER object that managed a
list of DESIGN_RULE objects.  I think the DESIGN_RULE_MANAGER would have
to happen before we start importing third party and/or creating our own
custom design rules.  Obviously this is going to be a large design
effort so before anyone starts writing code, we should create a proposal
so that we can come to some kind of consensus on the design and
implementation.
