commit a5138dec1ebd3cb82927f8de530315258f9875b5
Author: Michael James Gratton <mike vee net>

    Clean up ComposerEmbed a bit.
    
    * src/client/composer/composer-widget.vala: Removed uneeded embedded
      composer style - we're setting a min size for the composer on the GTK
      widget now.
    
    * src/client/composer/composer-embed.vala: Don't bother setting the HTML
      CSS class now it is unused. Use Source.REMOVE for callback return
      values for clarity.
