Enhance serivce project admin view

• state changes: admin may reject by mistake, but then need to approve. In the /project/connect-local-project-to-service.xhtml you can't connect a service, when there is an "APPROVAL_DENIED". You should be able to try it again, like when the flag is "DELETED".
• need to sort all projects by state, name, dates, etc (this is partially done). This means the /service-project-admin/index.xhtml page. Type is always the same, doesn't need to be shown.
• need to filter out deleted/pending/active from list of proj (configurable) (test project unlinked from my service and deleted, but I still see it in my list as service-project admin)
• need to search/sort projects and groups (this is partially done)
• service-project admin wants to see email addr of PI user who created that proj/group (I think this is done)
