[permissions] request/revoke (#46)

The introduction says:
> The initial intent of this document was to allow web applications to request and revoke permissions explicitly in addition to querying the permission status. This is an aspect of the specification that was controversial thus removed from the current document in a spirit of incremental changes: settling on a small API that can be improved. 

However, these exist in the document.  Should they be removed?  (I would say "yes".)
