Python-jsonschema-objects

+ Fixes an issue with how the uniqueItems validation was handled (h/t jepperaskdk)
+ Fixes 156

Several minor updates to build job configuration.

+ Fixes 143 by checking dirty flags for arrays and properties before revalidating. In order to allow for strict mode, this also passes the 'strict' flag down to the Array validator, in which case it will revalidate on every change.
+ Adds testing support for python3.7
+ Augments tests to run with newer versions of jsonschema
+ Recognize the `$id` property in place of the `id` property

Bugfixes:
+ Correctly apply v4 array validators even when the items constraint is a reference.

Features

+ Passing named_only=True to build classes will now restrict the
returned namespace to named classes. Fixes 141
+ ObjectBuilder can be instantiated with a custom resolver or validator

Bugfixes
+ v4 array validation terms now actually work

Misc
