Support Decimal

[jacobsvante]

>>> import dicttoxml
>>> from decimal import Decimal
>>> mydict = dict(mydecimal=Decimal('1.2345'))
>>> dicttoxml.convert_dict(mydict, False, 'objects', True)
TypeError: Unsupported data type: 1.2345 (Decimal)

(Well at least it gives this more precise error when you've merged #34)

You're right; dicttoxml should be able to accommodate Decimal values. Let me look into how best to implement this and I will push a fix shortly.

It looks like the most generic way to test if an object is a number is to import numbers and then:

isinstance(mydecimal, numbers.Number)

Unless I find anything better, I'm going to implement this.

[quandyfactory]

I went with isinstance(mydecimal, numbers.Number) as it seems to be the most generic way to test if something is numbery. Thanks for bringing this issue to my attention!

Thank you @quandyfactory for fixing this! (Unlike what the README says 😉)
