Button render equal setters, different properties.

[squarefrog]

In NUIButtonRenderer, padding is set to setTitleEdgeInsets:

    if ([NUISettings hasProperty:@"padding" withClass:className]) {
        [button setTitleEdgeInsets:[NUISettings getEdgeInsets:@"padding" withClass:className]];
    }

The same property is used for title-insets
    if ([NUISettings hasProperty:@"title-insets" withClass:className]) {
        [button setTitleEdgeInsets:[NUISettings getEdgeInsets:@"title-insets" withClass:className]];
    }

Is this intentional?
