Updated JSON protocol v1.0
This commit fixes a bug where the main view screen always claims that there are no identities on the device.
This is caused because the "load web view" helper function always pulls in the static contents of a particular HTML file.
Fixed that.
Added the necessary escaping to the correct strings to allow them to load as html.
