Backport changes from 1.2.0:
doc/index.htm.in,doc/manual.sgml,doc/survex.ent,lib/print.ini,
src/printwx.cc,survex.iss.in: Use http://survex.com/ rather than http://www.survex.com/ - the former is the canonical name and
www.survex.com just redirects.
COPYING,lib/print.ini,src/riscos/armrot.s,tests/: Update FSF address.
