Title: Add psource, pfile, pinfo2 commands to ipdb.

In addition, clean up the docstrings (so that `help ` returns more useful information.

One notable change is in the behavior of `pinfo`. Previously `pinfo object` did the equivalent of `object??`, i.e. what we'd call `pinfo2`. Is it worth "correcting" this behavior for consistency? I'll gladly discard the last commit (886a3ee) to preserve the existing behavior.
