some plugins need to be fixed yet: ticket, gallery, group, menu
- added current user to default models as "user"
- renamed in User: super_user -> is_super_user, env -> admin_env, pass_hash_salted -> is_pass_hash_salted
- now Users class has a WinixModel as a base class
some plugin calls have to be fixed yet
- added UserWrapper model with a pointer to User class
- removed from ItemContent: methods for accessing 'meta' and 'admin_meta', now ezc can iterate through Space classes
- fixed in env winix function: if there is "changeuser" parameter then we should only switch the user (not save anything)
- if there is a redirect and the json return answer is requested
then we send 'redirect_to' field in 'info' space

each html form has a hidden form_id and counter_id
counter_id on the client side is generated through javascript code
on the server the form_id and counter_id is stored in the session
after sending the html form the server checks the form_id and counter_id
