Not sure how useful it is since you can always force one section to have the
max number you want instead.
Anyway also added filling up with dummy sections to make shuffled numbers
on sections in the correct range from 1 to max.
Gamebooks are now quite playable in HTML version. Planning to
redesign inventory and codewords to be handled the same way, to allow
adding other things that behave in a similar way to a gamebook (eg
skills or spells). Also some obvious things are missing like being
able to check if NOT having an item or codeword, or preventing a player
from finding the same item twice (if redirected back to a section where
it can be found after dropping it).
Switched to text mark-up even more similar to org-mode, also more
similar to typical wiki mark-up, removing python-style format from
sections (but not from the templates).
