feat: add change password

[cootook]

What?

I implement a feature of changing password. Also I added a new template "message_page.html" and "change_password.js"

6 (issue)

Why?

It is a standard feature.

How?

Click "change password" button -> redirect to "change_password" view -> after entering current password, new one and confirmation, route handler comes into play -> rout handler:

• get values from the form
• check if current password is correct
• check if new one and confirmation are equal
• check if new one contains all required symbols
• generate new password hash
• update value "hash" in database
• check if login works with new password
• success message

Testing?

No

Anything Else?

"change_password.js" is almost the same as "sign_up.js". The both validate new passwords. They can be combined into one.

If login with new password failed it is better to write the old password hash into database.
