The new class AppWell implements the application favorite well in the Dash component. The previous AppDisplay remains for use in the More... mode now. Delete DEFAULT_APPLICATIONS; this is now in GConf. Rename getMostUsedApps to getTopApps since we now have the idea of explicit favorites. Delete some GenericDisplay-related calls from overlay related to the seletion - we'll reimplement keyboard nav in a more coherent way later.
