add options and readme to repo

these files are used in the gist to load the game into octo
correct ghost movement to screen left

the values that were being checked going from left to right were never
adjusted when I changed the ghost x momvement speed to 1
allow screen moving when human is running

this serves as a good way to reset a screen if the human is caught in an
infinite loop - just make sure not to make any levels that require
precision moving along the edge of a screen.
add level 1,2

note: this extends the the map to be 3x2
move level 0,1 to 0,2 and replace it

it was too hard/impossible to scare the human to the right from level
0,1 so now you won't have to do that anymore. the new level that
replaces it is a bit easier anyway.

this also fixes some collision detection with the open grave since it's
bounds didn't quite extend to the whole height of the sprite
