"Move" needs options "Left to Right" or "Right to Left" like "Copy"

[redtetrahedron]

In the folder comparison pane, when there is a "Left only" or "Right only" file, the "Move" option only has "Move to..." (which prompts for a destination folder). Frequently, I need "Move Left to Right" or "Move Right to Left". Currently I accomplish this by doing a Copy, then a Delete of the original, but it would be nice to have it in one step.

Added Move->Left to Right and Right to Left menu items to the context menu in PR #1732.
