Committed changes to Neubot database

In the last 2.5 weeks, Neubot contributor Alessio Palmero Aprosio and I have been working to: (i) move Neubot options into the database; (ii) explode each field of the results into a table. The former change allows to configure Neubot from the web user interface. The latter makes it possible to delete some ugly chunks of deprecated code. Still, there is a problem with speedtest duration that I need to investigate: test takes too much time for me at home. Then will come the first 0.3.7 release candidate.
