Performance decrease in 2.x

See original GitHub issue

Originally reported on Google Code with ID 2259

The following jsFiddles use the same code, only switching from 2.0.0 to 2.1.0 versions
of FullCalendar.  On a Core i7 FireFox the 2.0.0 versions loads 1500 events in under
a second, the 2.1.0 version takes 3 - 4 seconds.  Also the removeEventSource is extremely
slow.

2.1.0 - http://jsfiddle.net/indexic/L9z2Lbur/
