Fixes small bug that stopped sessions being filtered by Id
Add Vote page to front-end

- Moves voting to separate page
- UserId now stored in localstorage
- UI made more generic ('Option' instead of 'Restaurant' etc)
Results page now displays the name of the session
Fix integration issues

Having a Get(long) and Get(Guid) was causing server issues, as it didn't know which
to send to.

Also changes the Session Drop-down to use the Id, not UUID.
