Fix various mistakes and forgotten bits in previous 'Views' adding commit.

Core API code shall now be mostly functional again.

Asset API: add Views.

This commit add new 'View' forth layer, below history one (Revision).

It also adds a real UUID for the asset repository (as usual, asset
engines not needing it can just set it to zeros), will make Amber's life
(and all multi-repositories engines) easier.

Also fix one or two issues found on the road.

Code builds and links datablocks from libraries in the 'old way'. Real
test will come when re-enabling Amber and adapting it to new API though.

Disable for now asset engines (in preparation of core code changes).

Add basic addition support to create new assets.

Again, very basic and limited, to be fleshed out later.

Working basic repository list.

Also, fixed uuids generation.

And finalized/added to UI operator to add a new, empty Amber repo in
current directory.

Add basic handling of 'bookmarks' of Amber repositories.

Still some glitches to fix (and missing features), but mostly working on
basic level.

Fix two bugs with Amber engine:

* Reported number of assets was -1 in list_dir callback, incorrect and
would loop endlessly in case of empty repo!

* Conversion from main asset classes to their propertygroup
representations was not clearing extra entries in proplists.
