Big changes, alert notification via sms and email, new logging method.

[PedroSFreitas]

Attention, this pull should be reviewed.

The big changes are in: new database schema, SMS* and E-mail notification and new logging method.

*SMS notification wasn't tested yet.

We still need to implement a better way to handle email and sms notification. I'm not fully happy with what we have for now. Any suggestion is welcome.

EDIT: I could have squashed the commits, but I thought it would be interesting to leave this way.

Added "sudo" command to apt-get install as mentioned with @ozarchie. I still need to look at why virtualvenv isn't enabled when the script is done.

Merged upstream dev branch to remove the conflict. @TylerReedMC
