Add a login function

[Ranchino]

Create a form for login function. Already registered user:

1. username
2. password
3. logg in button

If it is valid then link to a new page else alert a error sign.

Create a form for new user with input

1. username
2. password
3. mail
4. registration button. Also when you have created a profile, a sign will show that everything is complete and now can log in. Then it will shift to login form.
