2.5 - Time operations to Animation Module

Browse Source 
Moved time_ops.c contents to anim_ops.c, as the operators there are applicable to all other Animation Editors too. anim_ops.c will therefore contain all operators which will apply to all Animation Editors (i.e. change frame, frames/seconds display toggle, and soon Preview Range tools).

As such, added new global 'Animation' keymap like for View2D and Markers, which will ensure that these tools can be accessed in an uniform way across editors. 
Note that the order that these things are added is important, as the Animation ones will often 'steal' events from the View2D and Markers ones if placed before the others. To prevent that, we'd need to be able to set boundboxes here...
