Implement a single fetch_info() function

This already existed, so I just had to define the api calls to use.
Unfortunately, groups return a similar group object so I also have to
define what return object needs to be looked up.  Additionally, IMs have
an extra "return_im" object that needs to be passed to get the full
channel info.
