adding hidden basic asp.net core backend (#30)
Base functionality:
DB
email sending
user registration & login
storing new characters and reading them back
Notes:
Functionality is "hidden" with no links pointing to it.
Most pages are scaffolded and not reviewed at all :(
local Dev db setup is pushed to git
NO local email setup :(
