Adds the following selection methods to the Sequence Editor:

Ctrl-RMB and Alt-RMB now call for different selection methods that are helpful when working within a single channel that holds several strips. The Ctrl modifier signals "Right" and the Alt modifier signals "Left".

Ctrl-RMB clicking a strip will select that strips left handle and the adjacent handle of any strip that abuts it on the left, allowing you to move the boundary between the strips without changing their outer endpoints. Ctrl-RMB clicking again on that strip will add to the selection all strips to the left of it, allowing you to slide the entire set of strips out of the way for a new one.

Alt-RMB works the same, but to the right.

Ctrl-Alt-RMB on a strip selects the surrounding handles only, allowing you to move the targeted strip and have the surrounding two strips adjust to follow.
