Webmail clients can register themselves with the browser using
registerProtocolHandler:
http://whatwg.org/specs/web-apps/current-work/#custom-handlers
https://developer.mozilla.org/En/DOM/Window.navigator.registerProtocolHandler
Firefox also ships with some common Webmail clients pre-configured
in preferences -> Applications -> mailto so they don't even need to
bother registering themselves.
