Bug 1379560 - Part 2 - Add support for custom default permissions in SitePermissions.jsm. r=Paolo

Part 1 added support for changing default permissions via pref. This
patch adds support in the frontend code, which is required to actually
make it work for most permission prompts.

This patch introduces the concept of SitePermissions.PROMPT (which
already exists in the permission manager) to distinguish between
the default UNKNOWN state and the explicit PROMPT state. They both
have the same effect (always asking the user for confirmation).
