The file url for each returned area file in get_area_files() is now
generated based on the request type. If AJAX request, a standard file
plugin url will be created. Otherwise, a webservice plugin file will be
created.
New return value 'icon' has been added to the webservice structure
external_files. This return value represents the relative icon path
for a given file. Also, get_area_files() from the core external utility
class now includes this information in its return.
Generated tokens should only read once.
Therefore removing the token column at the table view of the manage tokens page and the user's page.
The token should not be able to search.
