Fix formatting, some typos, and unused code, and add docstrings

- No idea why subclasses of ConversationTab were working before
    (info_header was overriden with None in __init__)
- Or why the date parsing worked (“Exeception”)
- Some more reformatting with pylint indications
- Document each module in the tabs module

+The XMLTab is here for debugging purposes, it shows the incoming and
+outgoing stanzas. It has a few useful functions that can filter stanzas
+in order to only show the relevant ones, and it can also be frozen or
+unfrozen on demand so that the relevant information is not drowned by
+the traffic.
