Version bump.

I think we should seriously consider the odd-even aproach.  That solves most 
of the ambiguity problem.  It uses the bottom bit of a numeric slot to 
indicate firm vs fuzzy status rather than our schemes for adding a "+" or "-" 
to the version string.

waf calls our version string MAJOR.MINOR.REV

I think we would use odd/even in two places, one for MINOR and again for REV. 
 git tags would only have even numbers in both slots.  We would bump the REV 
slot on an old release if we go back and patch it.
