Attachment 208836: Fixes capitalisation, cleans up logic per Stuart's comments
------- Additional Comments from Stuart Morgan
r=me. Works as advertized.
This shouldn't be checked in without the patch for bug 302865, or the
policy-editing table will be wrong.
Also needs "Allow for Session" added to the Localizable.strings when commited.
