Make blocks with more than one artefact in them (as what happens with listself) be expanded to have all of them displayed individually. This fixes the last major problem with migrating view templates.

Namely, when a block doesn't migrate properly.

Also reduced the size of resized images in views somewhat to work better on smaller screens.

Remove the title on filedownload blocks with more than one file in them. Correctly set the profile icon for profileinfo blocks. The general template now mostly migrates.

Make sure that when images are placed in views in 'listself' mode, they get put in filedownload blocks, which is more consistent for the upgrade. This makes the 'filelist' template migrate nicely.

The template itself is reasonably simple, the problems lie around the translation of certain template blocks to blocktypes - but these problems affect all templates.

It gets converted to a five column view (regardless of how many columns are actually used). The images are shown without their titles. All in all, this one migrates quite nicely, with the exception of images that are tall - the grid like effect is somewhat lost.

Anyway, it now migrates reasonably well. The labels are only output if there's artefacts associated with them.

Penny started this work but I'm taking up the rest of it, so there's some changes to how certain things work that I made while trying to understand the way the migration works.

Also commented everything.

Next work - test the PPAE migration, then on to the other templates.

There are lots of TODOs and none of the blocks get created.
It just moves stuff around according to the templates.

NOT TESTED.
