tidy up demo collections-3

[kjdon]

We want to get rid of the collection images - the scripts to generate them currently don't work, and they are therefore hard to edit.

We can use the same idea as general collection icons by having background images specified in css.

Revisit our idea about collection types.

Currently have public/private. Add a new type 'dec' or better word.

change

public true|false

to

collection_type public|private|dec

Library, when it goes through and makes the home page should put dec collections into a separate area, and tag the area/collection with dec so that a different background image can be used.

Incorporate David's group collections into this too so that the same mechanism is used.

Can we achieve this by adding some css or something into the collection?

The collections are in a collect group now. Will be good to have the nice background, but if its not done for the unesco cd then no worries.
