Iss #109 - Add fix for too long user agent strings

• Iss #109 (closed) - Add fix for too long user agent strings

Some user agents are longer than the size of the table column, which breaks those requests. As this is used just to more closely match the source, truncating isn't a problem as we don't care about the data but that it matches across requests.
