Title: Side-load specified relations into the Model identity map

It currently only works for singular associations (like belongsTo and hasOne). PluralAssociations do not properly register as loaded. If you have any ideas to get that working, I'd love to hear them here or at https://groups.google.com/forum/#!topic/batmanjs/xHvDCzQRoTw .
