Changed colour scheme (darker)
Add gaps between bars for periods <= 90 days (looks cleaner)
Only draw quarterly moving average for periods > 90 days
Fix red colour allocation bug for over quota notice
For daily remaining < 1000MB, show in MB instead of GB
Fixed spacing for stats to align vertically
Changed copyright notice on graph to show date fetched instead (sorry Peter Lieverdink!  The notice still remains in the RSS feed and the source!)
Merge my changes on v12 branch into master
Fixed bug: Daily remaining needs to be divided by BYTE_A_MB to draw correctly
