reworked without QR code on its own branch

This should be the latest version of my CV without the QR code that
Andrea disliked so much, with keywords moved to the end, and without the
chatty bits.  This is the version I am presently sending out.
changed to 12pt to avoid ligatures problem

There is a problem with ligatures in 11pt size.  Ligatures and the CMAP
work fine at 10pt and 12pt but not at 11pt.  I can't find the problem in
the 11pt compilation so to get it working for now, I reformatted the
text to 12pt which is probably easier for hiring managers to read
anyway.  10pt is too small.
