. Single web-app per Web Project changes implemented in Sandbox browsing view

- the web-app folder name specified at Web Project creation time is created by default and is the root folder for all sandbox operations
 - a mechanism for selecting a different root webapp (or creating new root folders) can be easily added later (when there is time…!)
. Removal of two public workflow actions that have no params and therefore don't work as public actions in the UI
. Fix to user sandboxes component to allow any user to always have action to delete a user sandbox
