Lazy loading in registry stores/output framework/models

[psychcf]

Dojo.data supports lazy loading of items. It would be interesting if there was a way we could implement this in the registry, since the registry is basically a modified datastore.

The way we can do this is by first off, telling the output framework via postdata to only return rows x-y, and then the filter() and all() methods can do some sort of lazy loading of items so that we don't have to waste time fetching the entire table from the DB.

I can't figure this out, I'm deferring this until 2.0, maybe we can get someone experienced enough with dojo.data to do this for us
