Overhauled the use of variables from CamelCase to _underscores_. This means that config files will need rewriting. This isn't such an issue, as I am now approaching release v1.0.

Setting logging level to DEBUG is also causing some issues- I shall look into this in the future.

The way plugins are named in config files needs looking into. the date_time plugin still needs to be referred to as dateTime, this needs to change.
