fix app to work properly with app.psgi as command-line or apache: * moved ajax route back to Routes::AJAX * Routes & Routes::AJAX load private instances of Reporter.pm, no longer shared * moved dbname logic from 2 routes files to Reporter dbname builder so only happens once in app routes.t uses Plack::Builder for app, same as app.psgi

bugfixes - cannot call main data var 'request' or clashes with D2 request

bugfixes - switched deployment to YAML file sessions as DBIx not working - maybe cookie handling issue; removed line-break in textarea markup causing 'required' flag to fail

modified HTML::FormHandler validation class to return same data structure as Data::FormValidator class
