[Feature Request] Multiple Cursors on Text Cells

[Luis Eduardo Velez Montoya]

This is a follow-up on #743.

It is possible to have multiple cursors on e.g. Code Cells, but not on Text Cells.
For my workflows, I am now forced to do the following:

1. Select text where I want to use multiple cursors
2. Extract into a new Cell
3. Change Cell type to Code Cell
4. Use Multiple Cursors to do the changes
5. Transform cell back to Text Cell
6. Put modified text back to original position.

That's an undesirable UX. I'd very much like to use the Multiple Cursors feature in Text Cells.
