Strict doesn't allow for semantically fine changes

This opens up to the use of any 1.9.Y or above (but below 2.X.Y) jquery and 1.2.Y or above (but below 2.X.Y) emberjs.

Since both these libraries maintain that they use Semantic Version Control we can assume (I believe reasonably) that minor and patch version changes won't break public APIs.

Basically I want to be able to use ember.js 1.5.
The semantics is a bit different from Ruby

Strict doesn't allow for semantically fine changes
Doesn't return relationships that don't exist anymore in DB or DS.Store

There are cases where a given record was deleted from the DB, but its
parent still has a reference to its ID. In that case, Ember.js will get
the reference ID, but the record doesn't really exist, and it will blow.

In this commit, we iterate over the relationships and check if it exists
either in the DS.Store or in the embedded records (inside IndexedDB). If
it doesn't exist anywhere, we simply not return the ID of the missing
record.
