This adds a popup for renaming.
- The popup opens with the text in an editable state.
- Pressing enter renamed the data and closes the popup.
- Renames active:
- Sequence Strip
- Currently mapped to F2 (using F-Keys so this can be kept a global shortcut for renaming the active item).
Currently this replaces the context sensitive file menu (which was nice but was a convenience and the file menu is always visible - so the trade-off may be worth it).
