Adds additional new dice [Map]

Places where the D6 and D20 spawned (the library and perma) now spawn with a dice bag (a new sprite with preexisting code). Said dice bags now contain a D4, D8, D10, D00, and D12 in addition to the preexisting D6 and D20 for a richer meta-roleplaying experience.

This also fixes an obscure bug where dice could be generated invisible because their initial face value was set to 0.

This also adds functionality to dice so that if a player actually throws a dice it will roll.

Additionally this fixes some grammar problems of dice descriptions, one of which being that they were not using the singular "die".
