New Feature: Be able to build own grouping of lines and assign meaning/map them to meanings

[SaphireLattice]

Current system just gives away everything that there is the moment you check off the Spoiler box, which is not very fun. Would be nice to allow the user to try and figure out the grouping, mapping and such on their own and then if they are really stuck, let them see the actual mapping.

Probably especially pertinent for common morphological quirks like pluralization and gerunds.
