Brush-up on Blackboard Bold

[Martin Vermeer]

This patch slightly improves the looks and behaviour of 
the various \mathbb set symbols, and calligraphic transform
symbols (any more of those?)

About quaternions, I believe the "H" symbol is in honour of 
Sir William R. Hamilton who discovered them:

http://www.maths.tcd.ie/pub/HistMath/People/Hamilton/Letters/BroomeBridge.html

...I believe the bridge in Dublin with its inscription still 
exists.

I would love to have all these symbols on the math panel, but 
fail to see an easy way to do that.

BTW what about adding a "Both" radio button to the Delimiters
sub-panel? I found out just now that clicking with the middle
mouse gives me a symmetric pair -- cool! (Yes I know, RTFM :-)
This should have a GUI equivalent IMHO.

Martin
