decimal.Decimal not included in DataTypes._numberTypes

[rhyek]

In version 0.5.0 I'm getting KeyError exceptions in Worksheet.py on line 143 for any cell with a decimal.Decimal value.

I tracked the error back to line 21 of DataTypes.py. Because Decimal values aren't being identified as DataTypes.NUMBER or any other type, they are never added to cell_cache. Thus the exceptions.

Importing the decimal module and changing line 21 of DataTypes.py to

_numberTypes = six.integer_types + (float, complex, decimal.Decimal)

fixes the problem.

Fixed in 0.6.0 released today - also added a test for this.
