[Feature Request] Add more context menu options to Screenplay Navigator

[Hyuri]

Right now, the context menu only gives us one option: Color.

But it would be very useful to also have these options:

• Add Scene — Adds an empty scene. Let's the user give the scene a title and a header (if the header is left empty, the header is set to same as the title. If a header is given but not a title, the title is left empty. The user can change these afterwards). If called on an act, adds the empty scene as the last scene inside the act.
• Add Act — Adds an empty act. Let's you give the act a title* and header.
• Rename — Renames the title of the scene or act*.
• Remove — Removes the scene or act.

This way, 1) it provides a quicker and more intuitive way of performing these operations, and 2) we don't have to open Scene Parameters every time we want to perform them

Note: This context menu should only present itself if the user clicks on an act or scene in the Screenplay Navigator. Clicking on an empty area should not bring this menu up.

* Right now Acts don't have a title, but it would be nice if they did. This way, we could have, for example, "Act 3" and title "The hero finds his true home". So I'll create another feature request for it.
