== Sequencer ==

This fixes the placement code of new files added to the sequencer timeline.

The old code tried to guess the strip position from the current mouse
pointer position.

Annoying effect: if you add a new strip using the menu, especially if the
file editor pops up, the strip ends up in nowheres land (most likely around
track 40, frame -200).

New behaviour: strips are always placed at cfra, which is the
sequencer equivalent to the 3D cursor (and that's where new objects in 
3D editing end up).

Bonus feature: we try our best to guess the right track by finding the
nearest strip by type.

The patch was inspired by 
[#32766] VSE: Add Strip on Current Frame

Thanks to venomgfx for the idea!
