Separate Login and Signup to individual pages

[Thenlie]

Deconstruct the Form page to make the login and signup forms have there own page and route. Very little restyling should be needed. This will mostly be file structuring and copy and paste.

• [x] Create login and signup routes in App.js
• [x] Create login and signup pages
• [x] Inject forms into there respective pages
• [x] Add logout to Navigation (conditionally)
• [x] Remove remaining Forms page/components
