Complete walkthrough of completed pages

Added routes for login/logout and profile pages - a complete walkthrough is now possible (i.e. one can register and browse the completed pages of the site). There are still quite a few pages that need to be even linked to.

The list of available routes/pages so-far:

`/` -- The home page with links to login/logout
`/user/register` -- The register page (temporarily does not send a verification email)
`/parent/42` -- The view parent profile page (where 42 would be the ID of the user)
`/therapist/42` -- The view therapist page (where 42 would be the ID of the user)
`/user/login` -- The login page
`/user/logout` -- The URL hit when loggin out of the site
`/about-us` -- About the site
`/terms` -- The terms of use and conditions
`/privacy` -- Privacy policy information

A lot of pages still need views, links to them, and to be routed to.
