Database skeleton

Created an .sql file to be imported in mysql to create the skeleton
Fixed brainfart

Missed one , in the db.sql file. It's now fixed
Added field for the key

Added an field for the pastekey for future usage
Removed mysql-configuration from config.js

Since I don't know really how the config works yet I decided to hardcode in the storage instead
Added mysql-support to filestorage

I chose to edit the filestorage since I use it on my server. Also encodes the data to base64 to get it into the database a little easier.
Comments in the code

Commented the code to show what's being done and reminding to change the DB-settings
Removed connect and end

Had to remove the connect and end functions. They was the cause of some strange errors and turned out to be non-critical
