v0.7.0 - Bug fixes, model hints, improved filter application and verification

Features:

• Add verify and apply options on filters. Used to define custom apply and verify logic, and deprecates overriding the resource methods apply_filter and verify_filter.
• Adds model hints to allow namespaced models and custom resolution of models to resources.
• Context is now provided to apply_sort method

Bug fixes:

• Fixed issues introduced in v0.6.x with resolving models to resources. Complex scenarios now should use model hints to assist the code in correct name resolution.
