Updated to v1.5

Trimmed parts of the code a bit more . 

I've made a few   changes to the game (which I feel improves some things).

Randomization (for certain effects in the game and for   when generating new maps) is fixed / improved.

The amount of rocks appearing on new maps   will tend to be more now (compared to earlier versions).

More gold now appears on new maps.

The Skeletons, though still with a mix of some random movements, they sometimes will be more likely to move towards the Player when/if they can. 

I feel some of these changes will help to add to the overall challenge and fun of game-play.
