Command-line script to convert 1.9 "text box" artefacts to 1.10 "text" blocks

[Aaron Wells]

In Mahara 1.10 we split the old "text box" artefact & block into two blocks: "note", which is backed by a "note" artefact type that retains the full "Text box" functionality, and "text", which is meant to be a dead-simple easy-to-use text displayer.

We also added an admin screen to allow admins to optionally go through and convert all the text boxes that weren't using advanced functionality (attachments, placement in multiple pages) and turn them into "text" blocks.

On a large client site, this was taking so long, that I decided it would be better to turn it into a command-line script. I've open this bug, to upstream that command-line script.

To test:

1. Install Mahara 1.9
2. Create some "Text box" blocks, with their underlying artefacts.
3. Make some text box blocks that are used in multiple pages, some with attachments, and some that just contain plain text.
4. Upgrade to Mahara 1.10
5. Run the command-line script.
