Myxer Development

API method call wrappers have been added for wallpapers and videos. Be aware, however, that currently only MyxerIndie profiles can add video content. All content manipulation methods use a common method that takes care of printing debug messages and calling lower level functionality to sign, build, and send requests. Uncommon parameters are passed to Myxer->ContentCreate() as the last argument. Now that boolean values can be sent, I also had to make sure bools are encoded in the query string and the data string that gets signed correctly.
