Merge branch 'master' into soc-2021-knife-tools

Knife: Added support for multi-object edit mode

Now you can create cuts on all objects in multi object edit mode.
- If a cut is started on a given object it can interact with that same object.
- The current object to be cut is switched based on the nearest edge to the mouse cursor, only when the tool mode is idle.
- When a cut is started in empty space it will interact with the last object the mouse was nearest before the cut was started.

Further improvements could include starting a cut in empty space interacting with the current object the mouse is nearest and allocating BMBVH's for each object on tool init instead of every time an object switch occurs.

Fixed memory free error

Small fixes

Fixed the error in calculating the value of start_frame and shifted call to
add strips for caching job to new function. Memory free errors still remain.
Much Faster and better response if thumb not cached.

The datablock must be in a frame inside the range to get a visible thumbnail.
