Change default method style for better IDE autocompletion
Make CommentsContainer use OverlayColourProvider
Refactor background creation in OverlayHeader
- When a selection is made (via the timeline) the selection tool should become the select tool. - When the selection tool is changed to anything *but* the select tool, the selection should be cleared.
Also tidies up radio button action firing so calling Select actually fires the associated action in all cases.
Now matches timeline colours (based on timing point).
Use type switch in SerializationWriter
Fix crash due to misordered selection events
Implement ability to create OverlayHeader with no TabControl
