Hide Pacman's initial location

[jleung51]

Currently, the game begins with Pacman at a corner of the map and right next to a Powerdot. As soon as the game begins, Pacman will eat the Powerdot and all Ghosts will be able to see them for 30 seconds.

Perhaps the Pacman should start half a black outside the playing area, so that they have more choices at which to enter the playing area, and so they do not necessarily have to be visible to the Ghosts for the first 30 seconds
