Flavor access list titles consistent capitalization.

On the flavor access tab of the edit flavor workflow, you
can select the projects that have access to the flavor.
Currently, the left list is "All Projects" and the right
list is "Selected projects". The "p" should be capitalized
in Selected projects.

This changes "Projects" in both list titles to be capitalized.

Fix endpoint error when running keystone on apache

When running keystone in httpd, horizon could not generate the
right keystone endpoint url. Fixes this issue by retrieving the
whole path from the service_catalog or OPENSTACK_KEYSTONE_URL
and generating a new url.

Update documentation to clarify Image Upload setting

The documentation at http://docs.openstack.org/developer/horizon/topics
/deployment.html#file-uploads states that the end user should change the
setting "HORIZON_IMAGES_ALLOW_UPLOAD = False" to disable image uploads.

This suggests that image uploads will be completely disabled, however it
will still be possible to upload images via URL.

This change adds this clarification to the documentation.
