Added Glastopf version number support to logs/db

[nsmfoo]

Added Glastopf version number support in logs and databases.

Verified to work for Sqlite, Mysql, Hpfeeds and Syslog.

Logstash output and possible others will need to be updated to make use of these changes

This solves the issue: #169

Please note that this requires a schema change ..

Also sneaked in a fix for the #245.
