This patch introduces the notion of a "domain" to the nitpicker configuration concept. Session policies always refer to a domain where multiple session policies can refer to the same domain. Thereby a domain provides a way to express the grouping of sessions. This is useful for applications that open multiple nitpicker sessions (such as Qt5 apps that use one nitpicker session per window, menu, etc.). We want to assign all those sessions to a single domain. The configuration looks as follows: <config> ... <domain name="default" color="#ffffff"/> <policy label="" domain="default"/> ... </config>
