Feature/jwt refresh (see description for testing)

[Alec-Watson]

Changes so that a access JWT may be refreshed and that the correct redirecting occurs.
Test cases:
Token functions can be found in securityFunctions.js

1. Token refreshing (set the generateToken functions lifetime to less than then the refresh token ie.3s). Token should be refreshed and actions should continue is normal.
2. Refresh token expiration (set generateRefresh token lifetime to be less than or equal to the token lifetime) upon making requests the user should be redirected to login.
3. Middleware checks such that the user can navigate when logged in and not when they are not.
