Since the configparser library by default parses keys case insensitive
(all lowercase), certain mappings, especially in the pulseaudio modules,
could fail ("internal" pulseaudio device names are matched against
entries in the configuration).

OK - so I have to admit I *hate* the fact that PIP seems to require a
subdirectory named like the library.
But since the PIP package is something really nifty to have (thanks to
@tony again!!!), I updated the codebase to hopefully conform with what
PIP expects. Testruns so far look promising...
Add two new parameters: theme and iconset
Add a placeholder class core.theme.Theme, an instance of which is passed
in to the i3 output object (which is the only object that should ever
have need of the theme, hopefully).
