Also removes the "tip" icon which doesn't work on OSX and isn't as
important as the graphics which actually convey information. Replaced
with the more generic "Note: " string.

1) Separate out CONSTRAINT types
2) Filter both source and dest pads/vias for drilled holes when doing
hole-to-hole checks. We were checking the items being put into the
DRC RTree, but not the items we were scanning.
3) Add hole clearance to Board Setup Constraints panel.

Set the netclass grid a bit narrower so it doesn't end up with a scroll
bar.
Load the constraints bitmaps on show so they get drawn (otherwise all
but those in the first sizer are blank).
This places the arc approximation setting in the kicad_pcb file and uses
it for all parts of the board rendering where arcs are converted to
segments. This allows the user to customize their speed vs. accuracy
tradeoff. The default setting of maximum error of 0.005mm is acceptable
for small boards on moderate systems.
For legacy boards, the setting is picked up from the board outline
thickness. If the board outline has mixed thicknesses, then the
max is used and a warning is displayed.
