remove $secure argument from all url() calls

this is step one in moving toward
 full usage of router->generate()
add JmikolaInsecureRoutesBundle to toggle routing ssl

This will allow us to add scheme requirements to our routing
configuration, but still allow us to disable it globally for dev
or other non-ssl usages

We are temporarily using a forked version of the bundle with a higher
symfony requirement.
add https to routes previously using url(,,$secure)

This adds the route requirement scheme for https
 to all existing routes that used
url('some_route', $param, true)
convert all url() param arguments from string to array

string params are still currently supported
