relocate template logic

RfC459 - adapt email function to handle multiple requests

added patient summary header to all request-related pages (phonelog, errorlog, email, data edits, unlock record, etc); option to switch off gross description field

new function to delete email contact address; updated mysql_backup.sh to new server config

print_view template bugfixes; adjusted print_view tt to handle email request

enabled emailing of anonymised reports to non-secure addresses; minor bugfixes

reversed previous changes to allow anonymised report to non-secure addr - still need to anonymise message headerpwd

allowed emailing of anonymised reports to non-secure contact address - moved check_email_is_valid() from validation class to C::Request::_check_secure_recipient(); request log view/print links hidden from external user - caused confusion

new screen_category table; moved screens 'type' col to category_id; modified all screening terms & screening tests admin functions to accomodate new screen_category table; removed ajax validation from screen description & lab test field_label as these use 2 & 3-col unique keys so can't be validated by AJAX; email reports function uses users secure email address as sender; modifed portal_access function to supply SHA1 hash of current date - so failed login not sent back to portal page without explanation; modified mail_reports.pl to use item names instead of table id accessors
