I changed most of the logger statements to use a class attribute, in
this way it's easier to identify which class it's logging them.

in some cases I leave a module-level logger, when we're either using
functions or when the module it's too small.

at the same time I did a general review and cleanup of the logging
statements.

a bit hacky and all, but this should launch the service
and allow interacting from the default site (localhost:9090).

this is the first example of a pyqt-js bridge, it's an interesting
mechanism that we can use more in the future.

no efforts made so far in authenticating the app.

this looks like a careless migration to twisted failures.
who knows how long this was like this, this should be covered by tests.
