Docs: contrib resource types appear in native resource list

[Zane Bitter]

e.g. the Nova Flavor resource is correctly included in the page for contributed resources:

http://docs.openstack.org/developer/heat/template_guide/contrib.html#nova-flavor-resource

but also appears in the list of OpenStack-native resources:

http://docs.openstack.org/developer/heat/template_guide/openstack.html#OS::Nova::Flavor

giving the erroneous impression that they're part of the main tree.

    Fix resources allocation in documentation

    Allocation of contributed resources generates
    incorrectly, so this patch fixes res allocation.
    Now contributed resources are in Contributed Heat
    Resource Types page and integrated are in OpenStack
    Resource Types page. Escaping from using env because
    of all_resources loaded from PluginMapping.
