AddApp and AppList pages: App List is taken from Local 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
