The name is largely irrelevant as it's only the creator of the file.

Change paths that were referring to view/view.php?id=..&artefact=.. to instead point to view/artefact.php?artefact=..&view=..

This is related to the viewartefactsplit branch. Now the existing code actually uses the new artefact.php script.

Changed all requires.
Also removed not used json/renderartefact.php

Implemented get_artefacts in the BlockType parent class, so that all children don't have to implement it.

The one exception thus far is the Profile Information blocktype, which needs to add the 'profileicon' field.

Renamed the 'view' parameter for view/view.php to be 'id'. 'view' will continue to work for a while.

view/blocks.php uses id, and id is used for other objects in the system, so it doesn't make much sense for this one to remain this way.

Remove a commented out block not needed.

First cut at the filedownload blocktype. There's a bug in the artefact chooser to do with ajax and multipage choice of artefacts that I'll deal with later
