[evolution] Replace 'interface' with 'iface' in the code



commit 5c60d57082ede522169b65efa67a1e268989b487
Author: Tarnyko <tarnyko tarnyko net>
Date:   Wed Feb 26 16:15:21 2014 +0100

    Replace 'interface' with 'iface' in the code
    
    Win32 headers have a #define for 'interface', which breaks the build
    when this word is used in the code, thus replace it to 'iface',
    the same way as GLib or GTK+ code use to have it. (See bug #722068.)
