Bugfix for feeds
    - removed categories related and up
    - load new books now working
    - category random now working
login page is free of non accessible elements
boolean custom column is vivible in UI
books with only with certain languages can be shown
book shelfs can be deleted from UI
Anonymous user view is more resticted
Added browse of series in sidebar
Dependencys in vendor folder are updated to newer versions (licencs files are now present)

"""Logging support for Tornado.
Tornado uses three logger streams:
* ``tornado.access``: Per-request logging for Tornado's HTTP servers (and
potentially other servers in the future)
* ``tornado.application``: Logging of errors from application code (i.e.
uncaught exceptions from callbacks)
* ``tornado.general``: General-purpose logging, including any errors
or warnings from Tornado itself.
These streams may be configured independently using the standard library's
`logging` module. For example, you may wish to send ``tornado.access`` logs
to a separate file for analysis.

# bytestrings. This is a bit of a hacky place to do this, but

# result are so useless (and tornado is fond of using utf8-encoded
