Added colour fade

Fades opacity between film ratings of 4 and 7.8. Also adjusts a:link HSL
color to darken high ratings.
Added brackets and decimal place

E.g. Shows "Expendibles 2 (7.0)" instead of "Expendibles 2 7"
Improved media type matching.

Updated regex as type wasn't being picked up. Changed video games to use
offset instead of giving them full marks. Decimal toFixed only called on
numbers.
