[Owncloud] Database access for apps.

[Côme BERNIGAUD]

I think owncloud should provide an API for accessing databases in the 
apps code.
Apps code should not contain any SQL code.
An app should be able to easily store and retrieve information linked to 
the current user.
"I, docsapp, want to save that the connected user have this object with 
this properties"

Basically the app should be able to do something like objectid = 
OC_Database::store(userid,id) (the object would be serialized to be 
inserted in the database)
And then OC_Database::get_object(objectid) and 
OC_Database::get_objectsids(userid)
Maybe all these should takes as first parameter the name of the app. (so 
that it use a separate base/table for each app)

This should preferably work both from PHP and Javascript.

Côme.
