Transition from NSS to CSS

[jeff-zucker]

This is a place to track a probable future transition of solidcommunity.net from using NSS to using CSS and especially how this transition can be made smoothest for developers used to working with NSS. Related modifications to the solidproject.org website are being discussed at https://github.com/solid/solidproject.org/issues/606 and https://github.com/solid/solidproject.org/issues/607.

I think that, other than prepping such transition materials, the biggest issues are :

• advance warning of timeline - even a very rough idea of when the transition might occur would be really helpful
• transitional test site - having the two running simultaneously on port 80 (NSS) and some other port for testing CSS would be really helpful and should perhaps occur sooner rather than later, Lots of things can be tested with self hosting but having an up-to-date online version would be better, especially in terms of registration / login / app permission flow.
