** Permissions **
ModHeader currently requires 5 permissions:
"webRequest" and "webRequestBlocking" are required in order for request headers modification to work. Because ModHeader doesn't know ahead of time which website the modification should apply to, it needs to request permissions for all URLs (3). "storage" permission is needed to save settings to the cloud. "contextMenus" is used to enable quick pause/unpause by right-clicking on the icon.
