This commit allows more flexible and consistent theme overriding rules for each Widget. There are 3 levels of customization. 1. Global theme (yui.theme) this is the default theme for every Ui 2. Ui theme, this overrides the global theme and provides a default for every Widget of the Ui 3. Widget theme, this overrides the Ui theme for a single widget This commit also allows themes to specify a font field. This replaces the sparse color, font and cornerRadius field often provided by each Widget. Widgets and Uis may also partially override a theme by specifying only a few fields.
