Animation Goodie: Cyclic "Extrapolation" can be toggled from the "Set
Extrapolation" tool again

Added "Make Cyclic" and "Clear Cyclic" options to "Set Extrapolation"
tool (found from Channels menu) in Animation Editors. These options
simply add or remove (respectively) Cycles FModifiers from the
selected F-Curves, making them have cyclic extrapolation with a single
click, instead of having to go through the FModifiers UI (or Graph-
Editor only "Add FModifier" operator), which should make it easier to
do this apparently common chore.
