As a xoder I want “Open Recent” feature so that I can continue working on my projects quickly

MRU lists are super-handy:

In our context, we should display filenames for xodballs (my-proj.xodball) and directory names for multifile projects (my-multi).

Acceptance criteria

• [ ] I can see up to 10 recent projects in “File → Open Recent”
• [ ] Open / Save All / Save As move the project to the top of MRU list
• [ ] If the list is empty, it expands to a disabled item “no recent projects”

Out of scope

Invalidating MRU list paths. It’s OK to show an error after an attempt to open if the project has gone

I would also like to have this feature, I mean almost all programs I know offer this because it is simple and helpful.
