checkInvite no longer loops over all invites and checks for expiry, that
functionality has moved to checkInvites. Couple more rogue print
statements removed aswell.
Modifying settings also formats it nicely, as a bonus.
Also we using shortuuid instead of normal uuidv4 now because its the same
length as what I used in the python version.
Python utility included to convert config-base.json into a new version
which includes lists that define the order settings should be displayed.
admin.js edited to recognize this.
The invite route no longer calls checkInvite, instead just chekcing the
invite exists. This speeds up page loading. the 404 and invalidCode
pages are now loaded when necessary.
