Sitter Login Re-added

[Astaroth]

Sitter login was re-added and fixed so you wouldn't be able to login on a non-sitter account.
So far the sitter login grants full access to your sitter but later on you will be able to set his permission to certain pages.

How does sitter login work ?
You have in the options page a field called "Sitter", write the sitter's username there and he will be able to login with your username and his password from this page
