Issue with mixed type attributes

[fuzzycode]

Attributes that are expected to be string/unicode will be int if the attribute is strictly alphanumerical.

For example a episodeName attribute would be expected to be string and in most cases it will be a string, but for strictly numerical names, the attribute will be an int.

This is due to pytvdbapi not doing any type conversions and relaying totally on the data that comes out of the xml parsing.
