- Shots now attempt to stay connected to each other when modifed.
-- Shots appear "connected" in the shot track so that when one moves, the previous one shrinks and next next shot grows.
-- Holes are filled for deleted shots
- Various low level shot rendering fixes

Top level key area nodes were not being handled correctly by the entity walker. Changed HandleKeyAreaNode to require the owner node for bounds testing purposes.

- Added FSequencerSnapField to simplify snapping calculations and related code.
- Formalised IMarqueeVisitor as a more generic ISequencerEntityVisitor that can be used to walk a range of visible sequencer entities
- Updated FMoveKeys drag operation to use FSequencerSnapField and corrected snapping code
- Track area geometry is now cached in SSequencerTrackArea to simplify SSequencer::GetVirtualTrackArea
- Fixed grouped keys swallowing each other when dragging other keys over the top

Conceptual changes:
- SSection is no longer responsible for drag operations. This alleviates mouse capture fighting and event ordering issues to do with both SSequencerTrackArea and SSection wanting to potentially handle drag-like events.
- ISequencerEditTool can be implemented to define interaction logic for the sequencer as a whole.
- There is only ever one tool active at a time. This is set by SSequencer::SetEditTool.
- Edit tools are responsible for handling mouse input based on the current environment
- Sequencer hotspots define particular points of interest on the sequencer UI such as keys, sections etc. Hotspots can optionally define a drag protocol. This may or may not be honored by the current edit tool.
- FVirtualConvertor has been formalised as FVirtualTrackArea which provides logic for converting between virtual and physical track area space, as well as hit-testing logic.
We currently have two tools: move (V) and marquee (M) selection. Marquee selection has two modes (key and section selection) which can be toggled with the toolbar button, or by pressing the hotkey multiple times.
