Used DateAxisRenderer to draw 'All Months'. Still suffers from too much padding in some cases (when the number of months cannot be divided in a 'nice' number?)
Added config.php to ignores
Instead of pad-0, calculate our own min/max to create nicer ranges
For 'This Month', also use nicer min/max.
Added 'average' line, like in swf version
Merge pull request #3 from mjholtkamp/master

Better handling of axes for the "All Months"-view, using DateAxisRenderer and better min/max. Finally, also an "average" line.
