remove extra " from DashboardWidget
fix groupPricingService class
re-add per "app" template extension setting in RouteResolver
change all admin template refs to html.twig

Of course now this breaks everything. This isn't really a problem
since they will have to be converted anyways
convert some admin templates to twig
introduce admin about controller to handle phpinfo for twig
remote prototype scope from templateView service
convert admin accounts template to twig
convert admin pagination template to twig
 convert admin index, reset_password and account_show to twig
convert most of the rest of the admin bundle templates to twig

This includes all the templates but installation,static pages, and
default_layout.
various block fixes to make them show again
fix jquery ui icon references in zenmagick.css
add missing route for block group admin
remove manual title setting from legacy config template
fix localizeddate filter usage in order template
rebuild admin default_layout in twig

This is the quickest way to get the current layout working. The menu
code is very rudimentary. It will be refactored during the next phase
of admin development.
the absolute simplest way to convert zc_admin template to twig

Most of current zc_admin.html.php template contents
should be refactored
remove view: key from zc admin routes
add twig globals that match current template helpers by name

This is the same as the $admin, $form, etc variables in the php
templating implementation
