ported r2634,r2636 & r2716 to the test-suite branch, corrected test_float.py
commands used svn merge -r2633:2634 svn+ssh://varioustoxins@.../svn/relax/1.2 svn merge -r2635:2636 svn+ssh://varioustoxins@.../svn/relax/1.2 svn merge -r2715:2716 svn+ssh://varioustoxins@.../svn/relax/1.2
these changes add the ieee-754 nan/inf code, add nan catching and change Test_float so the first unit test works. I also tidied some conventions
