bitbake: toasterui: add extra debug and development infos

We update and add logs throughout the code in order to help
with development. The extra logging is turned off by default,
but it can be enabled by using environment variables.

All logging happens through the Python logging facilities.

The toaster UI will save a log of all incoming events if the
TOASTER_EVENTLOG variable is set.

If TOASTER_SQLDEBUG is set all DB queries will be logged.

If TOASTER_DEVEL is set and the django-fresh module is available,
the module is enabled to allow auto-reload of pages when the
source is changed.
