[feature request] Ability to subscribe an /e/ account at initial startup

When starting the OS for the first time, the user has the opportunity to input his /e/ account details. But not to create an /e/ account.

This would be useful specially for casual people who buy a pre-installed devices and therefore may not be aware of the opportunity of the /e/ account and where to subscribe to it.

It is much better to add the /e/ account at startup than to add it later. Adding it later requires some more knowledge from the user (and in addition there seem to be a bug that requires reboot before files start to be synced).

Suggestion : offer ability to subscribe an /e/ account at initial startup, directly from the device itself. With some explanations of what the /e/ account allows (important for the casual user is the backup/syncing of his contacts and photos).
