enable converting cti files to xml with molecules with non-integer values of the atomic composition

[GoogleCodeExporter]

When using ctmethods it is not allowed to use molecules in the definition of 
the species within the cti-file with an atomic composition which is not an 
integer. E.g. C12.5H33.22 would not work, but C12H33 would work. But when using 
sum-formulas of multi-component mixtures this might be necessary.

The problem is due to the definition "def getAtomicComp(Atoms)" (~line 367) in 
ctml_writer.py:
d[b[0]] = int(b[1]) and can easily be solved when this line is changed to
d[b[0]] = float(b[1])

it worked with my cantera-version. 

The changed version is enclosed.

Fixed in r2989.

I'm not aware of any cases where this capability has been exercised in Cantera, 
so proceed with caution, as there may be other places where it is assumed that 
the atomicity of each element in a species is an integer.
