Fixed errors in repo name for deployment.
fast numbers now comprehends 'inf' and 'nan'.

The conversion functions accept 'inf' and 'nan' (except for the int
ones) and forceint converts 'int' to sys.maxsize but still does not
accept 'nan'.

The test functions do not recognize 'inf' and 'nan' unless the user
wants that.
Added missing Py_TOLOWER from Python 2.6.
Added documentation for 'inf' and 'nan'.
Merge branch 'develop'
