(non consistent edit pin per pin option and erroneous pin number edition)
Pcbnew: fixing a problem in dialog design rules for small screens (768 pixels height); Better look on bigger screens
* Added exporting of netclass vias to specctra_export.
* DIALOG_DESIGN_RULES now remembers it last selected TAB and screen position and
window size, and its grid columns are automatically expanded to fit the
column titles. Remembering screen position and size allows someone with
multiple monitors, to have a given window always come up on the monitor last chosen
for it.
