added db and maximized fixtures; some names changed

Added database fixtures, so you can run your tests also on an empty appliance.

Sample jenkins run of a cfme_pages/tests on an empty appliance:
http://hudson.rhq.lab.eng.bos.redhat.com:8080/hudson/job/apagac-cfme-pages-tests/27/HTML_Report/

Errors:
 - test_catalog: known error, opened issue
 - test_logout: random error.
 - test_utilization: this has been fixed, but issue is opened on another one

Everything else should be working.
