=== Animation ===

Patch #4044 patch to change the step when changing frame with up or down arrow keys.

This adds a per Scene setting to specify the number of frames skipped by the up and down arrow.
This setting can be changed in the Timeline header and in the Anim/Playback section of the Scene settings.

Upon loading a file without that setting or creating a new scene, it is set to 10

Also fixed the Start and End frame buttons in the Scene buttons to do a proper refresh.
