Created initDarkness label
Created the initDarkness label in 00early.dark.rpy to get the results of parsing the map files.
Displayable Tiles
We are now able to display tiles, next we need to manage reading a tileset from and archive, and then creating a screen for displaying boards on.
Fixes some issues with last commit
From the last commit there was an error where we could only call the tile sprites to be shown and it would only work if there were at least 2 sets in the .dark.tile file. Also added variables for each set to alter the x and y offsets of the board. This was a mistake that needs fixing as the offset should be a part of the board info.
