In windows (not sure about linux) "localhost" will be parsed in HOSTS file, so it takes too much time.

It may seem that this commit is rather big, but it's not. Don't be afraid, just read the message. Recently we have understood that it was a bad idea to store rights for pages in a database. So I decided to move the information to PHP layer and make it more clear.

When you write a new controller in Admin/ Dean/ Student/ folder, you should explicitly extend one of Controller_Environment_* classes, and all specific checks will be done there. Additional advantage is manipulating $user variable, so you will have access to extended fields of user, ie User_Student contains StudentID, but User_Teacher does not.

Also, prefer -> operator to []. The reason is simple: IDE shows hints and mismatches only with the first one.

The second important statement is User::checkAccess(User::RIGHTS_*) — call it at the top of *every* function in the Handler/ classes. Exception will be thrown, if user doesn't have enough rights.

NB. If you want to overload "before()" function while extending Environment_* controller, do it in the right way:

    public function before() {
        parent::before();   // always first

        // any magic you like most
    }

It will be loaded _only_ on the sign in page!

But we still have another helpers.

So you have access to them from any module / macros.

* Model User has constants to check access for pages
* Some routes are moved to separate files (app/routes/api)
* New abstract model Container for complex objects like Discipline & Student (with -> access operator)
* New DeanOffice controller with access checks
* New SQL procedure to get info about students
* Profile page for students (/dean_office/students/127)

1) Now user info stored in session
2) Merge GetAccountInfo & GetPersonalInfo
