[TriEmbed] removing the "bumps" from OSH Park boards

I found the perfect tool: a large diameter grindstone in a fixed
position Dremel (i.e. mounted in a press or something). It's perfect for
very quickly knocking the bumps off and you can make the edges as close
to flat as your eyesight and hands allow. Getting rid of the whole bump
is important for minimizing the hassle of pasting with a stencil (any
little bump can cause the alignment to be messed up). But it also makes
the boards much more attractive.
But folks, be sure to wear a good mask. I can only think of one thing
worse than fiberglass dust getting into the lungs. The good shop masks
with the "easy exhale" valves seem to work very well for me.
