Merge branch 'master' into asset-engine

WIP Add asset sub-data dependency info.

We need that info (knowing which non-asset IDs are used by which asset-IDs),
otherwise managing reloading, updates etc. of assets would be impossible
(or rather, would leave a mess of unused IDs behind them).
Only partially done, non-functional yet.

This commit also adds asset repository references in libraries.

Assets: add uuid to linked data, write and read it from file.

Note that this is only very first steps, I think we'll need to 'propagate'
uuid to all data used/linked by asset itself, otherwise most things won't get
updated/reloaded. Still have to think about this.
