While 1.1.1 is required for PHP 7 support, we technically only depend on the 1.1.0 API (this is more relevant for HHVM).

This ensures that the library's default type map (i.e. model classes) are used for manually constructed Database and Collection objects.

This adds inheritance of the Database's type map option, which should have been added in 330e1e30.

Property access, which was already enabled on unserialization, allows code to work with the model as it would the driver's default stdClass

This should be considered an internal interface until driver interfaces are available and we can use ServerInterface (see: PHPC-378).
