Rewrite the mail label code from top to bottom.
- Kill the e-util-labels API and read label information into a single-column GtkListStore. Use GConfBridge to automatically keep GConf synched with the list store. - The list store (a singleton instance) is stored in EShellSettings so it's available everywhere. - The list store serves as the model for EMailLabelTreeView, which itself is embedded in EMailLabelManager; a complete label management UI as seen in the preferences dialog. - EMailLabelDialog is used to add or edit a label. Avoid using a color button, instead embed a GtkColorSelection directly in the dialog so everything is in one window. Open issues: - The weird toggle/color/text menu items in the popup menu aren't there. For now they're just regular toggle items. I'll deal with it later. - Filter intergration is broken at the moment. svn path=/branches/kill-bonobo/; revision=37233
