Added Rename and Shot Viewer tools

Rename panel: batch rename selected objects (or their materials) as
prefix_name_side_number_suffix. Numbering continues after existing names,
object data follows its object, and a preview shows the result.

Shot Viewer (button in the Tools panel): opens a window with its own
workspace showing the shots (sequencer scene strips) through their camera,
with the edit's sequencer at the bottom. Scrubbing the edit switches shots,
playing a shot moves the edit playhead, Loop Shot loops playback on the
shot. Shots can be added and deleted, and character / prop rigs selected
in pose mode from the sidebar.
