Prepare for rewrite on several functions

User struct now exports everything, encapsulation is not necessary
over here. Instead of introducing a new variable uInfo we'll use
user.User and pass that. Handlers & related functions will be
rewritten to work with this change. This will make it easier to work
on later as the program grows. I'm also rethinking error handling.
