Cleanup code

get rid of newlines and old comments
Rename getTileScore getTileValue

getting the value of a tile
Fixed bug with Trolls

WE HAD TO USE A FUCKING STRING REPRESENTATION OF THE FUCKING TILE-TYPE
INSTEAD OF AN ADT WHICH WOULD MAKE FUCKING *SENSE* BECAUSE OF ELM'S
STUPID-ASS BULLSHIT PERTAINING TO NOT BEING ABLE TO PUT A FUCKING CUSTOM
ADT INTO A FUCKING DICT! FUCK! FUCK FUCK FUCK FUCK FUCK!!!!!!! AVOIDING
