Query-retrieve might be broken for SR as part of CT studies

[Ed McDonagh]

Need to test further when I'm back on site. Applies to 0.8.0b2, not sure about 0.8.0b1.

When checking SR type, _query_images isn't functioning, so always returns zero images.

Adding in Study Instance UID to Image level query. Should be the fix for ref #618

Bumping version numbers for 0.8.0b3 release. Also added refs #616, #618 to changes and removed in-page link (hash) from highsoft link as it may be what is causing readme to nor format on PyPI
