fixing & standardizing logging

Django logging was changed in 1.3 and logging no longer happened; added
a basic logging config into settings_local so customization is
available to end sites (see next commit), and changed the default
logger init (in all files, at this point) to;

```python

import logging
log = logging.getLogger('rooibos')

```

also PEP-8 and/or syntax fixes (there was an import error in there
somewhere for sure...)
small settings_local fixes
re-enable debug_toolbar
