* Effectively this allows to edit two Sites at the same time in two
differents tabs
* It also to not change the site you are editing in a tab by changing it
in another tab

* By default Apps are now deployed to a Crib with a different domain
* App JSON has been updated to have necessary parameters for this
* App list redirect to url list, editor, and export pages with the
crib_enable parameter of the applications to have these pages work
 with the crib of the application
* URL List, Editor and Export pages set crib enable url when the
parameter is provided

* Also add the possibility to handle relative url

* Instead of getting the List throught the local storage we get it from
a http get. This allows to edit another domain and still have the app
list functionnal.
* Add mecanism to quickly switch domain edition when updating app list
in order to be able to edit the current app list on the current domain

We are now able to calculate it on our own so it has become bothering
to have it by default

* The idea is to not overwrite the app list of the user upon CribJS
update
* Add Application_path parameter in order to edit the whole application
when the default landing page of the app is not index.html
