#890 lxpanel/dclock: does not honor panel font config immediately

[Mamoru TASAKA]

Original downstream report: https://bugzilla.redhat.com/show_bug.cgi?id=1261464

Currently even if user change panel font configuration (like color), dclock plugin does not honor such change immediately. Only when the clock string changes the panel font configuration is applied, so there may be about 1 min delay before font change is applied.
