Allow project dashboard to be a widget thing

[airtonix]

What would you like to be added?

Currently you can only view projects by using the command "View Projects" and then changing the dropdown to the project you want.

instead, lets make a thing that can be put on any page via codeblock:

```project
Name: My Project

Views:
  - Type: Board                # object mode
    Columns:
      - Name: Backlog
        Pinned: true
      - In Development         # string only name
  - Table                      # shortform of Type

Colours:
  - Id: colour-id
    Views:
      - Board
    Colour: violet
    Where: tags
    Condition: has-one-of
    ConditionArg: story
```

Now this can go in a markdown file for which we can use with Folder Note

This now lets us treat the main note for a folder as the project view for that project.

Why is this needed?

So we can decide where our Project dasboards appear.
