Access Flipbook Modules directly through a query string

1)Access Flipbook Modules through query string:

for flipbook 3 (and actually 2 as well) you can append a query string to the URL to automatically load a module once the flipbook loads.

to use the popup, simply append ?popup=xxx to the end of your link URL (eg.  http://viewer.e-digitaledition.com/t/10610?popup=archives)

where xxx can be: archives, email, bookmark, help, subscribe

the popup will only work if:
- the ad widget is not enabled (it takes precedence)
- no authentication is enabled where the user has to log in (the login popup takes precedence)

note: do not confuse ?popup=subscribe with ?showSubForm=true

?showSubForm=true is used when the login form would normally display (i.e. authentication is enabled) but instead the full subscription form is displayed

?popup=subscribe should be used when subscription module is enabled but "bypass authentication" is checked. Then this will simply popup the optional subscription form, much like clicking on the "subscribe" button on the bottom-right (i.e. subscribe button widget)

This functionality is only supported in flipbook 2 and 3.

On mobile 3.0 however, ?popup=subscribe is still usable. It will load the subscription form instead of Mobile 3, but will include a "cancel" option that will redirect to the mobile 3 experience
