Adding ResetPassword route and container

[janet]

• adds ErrorMessage component
• updates LoginForm component to fully connect to store because it needs the error passed to it (was having issues passing the error to it and having the component re-render, this meant the test was also too difficult to perform, need to relook at this later)
  • adding isAuthorized state
• adds /reset_password route
• adds ResetPasswordForm component (also similar to LoginForm, and thus doesn't have a test)
• adds TextFieldInput component as part of refactor of LoginForm
• adds ColumnWrapper
• moves fixtures into tests/directory so we only define fixtures once
  • [ ] move mockApiResponse to /tests directory
• change 'process login' to 'authorize'
• adds authorize.js with login and resetPassword requests, these are tested in Login/sagas.js
  • [ ] need to test resetPassword
• salts text field password before sending to backend
• updates fetch requests to credentials: 'include' so that requests send cookies for Flask cookie user login sessions
• installs bcryptjs, btoa, (for password encryption)
• installs localStorage for login authentication
• updates sinon for stub feature
