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)
moved get_pds_data() block to Role::PDS - don't need 'with' followed by 'with' any more in Validate; made logo img-responsive class to enable dynamic resize; tt layout rearrangements
removed params & config tokens from before_template hook (automatic anyway); renamed search() to to disambiguate from 'var'; moved content of _validate_form() & _validate_nhs_number() back into routes (only 2 lines each); Path::Tiny in Role::PDS
