adapted request forms upload function to provide encrypted 'centre' token so FileUploader puts request forms in correct location (leeds/uclh)

bugfixes: L::Local::LIMS supplies CGI::Simple object for C::R::PDF to call query() method - for mail_reports.pl; update_request validation removes jquery watermarks on date/time fields; removed BEGIN block from request_forms.cgi and loaded FindBin from local::lib to avoid system Carp issues; changed request_report to request_report_view in chart.sql

moved Devel::Cycle find_cycle() code from cgiapp_init to teardown, and made it permanently active for non-fastcgi requests - found and fixed many circular refs inside callback subs; new resources menu items; new file-uploader scripts
