Minor EMailReader cleanup.

Add a load_string() method to EWebView.  Have EMailDisplay override
load_string() and check that the formatter is not busy before loading
the string.  Have EMailReader call e_web_view_load_string() directly
on the EMailDisplay instance, and eliminate update_webview_content().
