New voting system

After having numerous requests to implement a new voting system, seeing the downside of the previous, simplistic system and discussing this with the staff, I have now implemented a new 4 scale system instead of the old "good vs. bad" system.

Hopefully the new system will give more fair votes to the songs. You now have these to choose from:

- BAD song
- BELOW AVERAGE song
- ABOVE AVERAGE song
- GOOD song

So... Get busy voting on your favourite songs!

Cheers!
