Spreadsheet: add boilerplate code for new editor type

This adds the initial boilerplate code that is required to introduce
the new spreadsheet editor. The editor is still hidden from the ui.

It can be made visible by undoing the change in `rna_screen.c`.

This patch does not contain any business logic for the spreadsheet editor.
