first draft of dashboard view; first draft of quick search but not able to share find_requests() with main search as we need 'AND' not 'OR' logic; combined _process_tests_complete() logic with _get_request_status_query_args() for tests_completed; moved jquery version from 1.4.2 to 1.8.2; moved devel server to port 8000

modified LIMS::cgiapp_prerun() to check for new messages after re-authentication - will mainly benefit external users where idle timeout equals ajax poll new msgs frequency, so will never see ajax notification
