The first ajax load fetches the template and puts it in localstorage + a js var
The second load gets it from local storage, but does not put it in the js var.
The pix_icon helper expects it to be in the js var always.
This needs to be done before we can expose any webservices that
change state, or return private info to ajax (to prevent CSRF).
Currently there are no webservices exposed to ajax that meet these
criteria - so this issue is to prevent future security issues.
This is a new script that can call any function in the built-in AJAX webservice. This is
a new system service that is added at install time (like the mobile webservice). It has no
protocols added to it, but it accessible by a new ajax script /lib/ajax/service.php.
Requests and responses to the script are required to be in json format, and multiple functions can
be called in a single request.
