KRACOEUS-7578

- Added central admin lookups
- Added maintenance lookups
- Added sys admin lookups
- Added Quicklinks link to header
- Added unit portal links
 
And shouldn't these actually be similar to other groups in the header? Like
```
	<bean id="Kc-Header-Researcher-IRBGroup" parent="Kc-Header-Researcher-IRBGroup-parentBean" />
	<bean id="Kc-Header-Researcher-IRBGroup-parentBean" abstract="true"
		parent="Uif-MenuList" p:headerText="IRB Protocols">
```
