[geary/wip/765516-gtk-widget-conversation-viewer: 95/207] Remove redundant Geary.Email arg from ConversationEmail signals.

[Michael Gratton <mjog src gnome org>]

commit edf1bb19072ec0cd8fd04655311f2aea81192919
Author: Michael James Gratton <mike vee net>
Date:   Tue Jun 21 14:48:24 2016 +1000

    Remove redundant Geary.Email arg from ConversationEmail signals.
    
    Since the ConversationEmail instance is also passed to signal handlers
    and the view's email instance can be obtained from that, also passing the
    email instance is redundant. Don't do that.
    
    * src/client/conversation-viewer/conversation-email.vala
      (ConversationEmail): Remove Geary.Email from signals where
      present. Also rename ::mark_email_from to ::mark_email_from_here to
      make its operation a bit more obvious. Update call sites and handler
      implementations.
