Update WebUI calls to use extensions namespace, update IDs in c/b/r/extensions

Update WebUI calls to use extensions namespace, update IDs in c/b/r/extensions

Update calls to ExtensionSettings, ExtensionCommandsOverlay, and PackExtensionOverlay to use extensions.X so we don't have to declare each outside of extensions.

Update HTML IDs in c/b/r/extensions to use-hyphenated-case.

Quick change to get rid of those "// Update the C++ call so this isn't
necessary." comments. Please review when you get a chance. =)

Added in the updated ID style (at least for c/b/r/extensions) to be consistent.

Cheers :)
