0.31.0 - /about resource, IE Mode Request Improvements

• Now provides a way to query for the /about resource and builds an object from the returned value
• Fixes IE Mode request to detect request length for native XHR requests to fix requests made from more modern IEs (10+) that don't use XDomainRequest but still have the length limitation. Doing it across all native requests was simpler than doing a feature detection just for the newer IEs. This might also help with some hosts that don't support long query strings.
