* gtk/Button.cs : Some nomenclature changes. s/EmitClicked/Click, etc. We need a consistent way to deal with naming clashes in gtk's method and signal namespaces. When clashes exist, events will be made past tense and methods to programatically emit events will be the present tense (e.g. Clicked event and Click method). svn path=/trunk/gtk-sharp/; revision=1116
