modified input form to work with IE8 - doesn't support placeholders or client-side validation; new requested_by field, moved taken_by & datetime fields to pdf form
replaced Role::PDS get_username(), get_user_ctr() & user_profile() methods with session data; google ajax url needs to be https if vcalled over https connection ie remote user
moved username & centre param handing to session; simplifed separate db calls to single model() function; app_version git log function; merged Ajax class _get_referral_sources() with autosuggest_location route
new tests using LWP::Protocol::PSGI; new 'helper' class RequestForm::Test - loads Modern::Perl, Data::Dumper, etc & lib paths (same function as test-lib.pl but also exports packages)
