When access is denied, also provide when possible and wanted, the needed
permissions so that in the future, user will be able to ask for
permission easily.
Renamed previous user handlers as admin user handlers.
Added non admin user handler /user/{uid} .
Add new `send_...` response to `CMS_API.response_api`, and use them
instead of `create {...RESPONSE}.... ; execute`.
Fixed potential issue with storage mailer initialization if folder does
not exist.
Added utf_8_encoded helpers function on CMS_API interface.
Fixed a few unicode potential issues.
Removed a few obsolete calls.
- Added $theme_path, $base_path
- Added CMS_RESPONSE.module_resource_url (...) instead of using hardcoded "/module/" + name + ...
- Use base_path rather than base_url (note ROC CMS is not yet working with EWF standalone "base" url option)
This optimises a bit the routing map, and make cleaner separation.
Make the base url for admin pages customizable via `administration.base_path` variable in cms.ini
note: could be /admin, /roc-admin, or ..
It is possible to have a specific theme for administration via the variable "administration.admin"
