F-Curve Modifiers: Cycles Modifier

* Added GUI and fixed bugs in the Cycles Modifier. This replaces the old Cyclic Extrapolation settings, giving more fine-grained control over the results. You can now specify whether the keyframes are repeated before and/or after the range independently, also, the maximum number of cycles on either side can be controlled.

* TODO: it would be nice to have the last value held for cyclic+offset.

* Deleting modifiers now works
