Man Off Mars 1.2

I worked a bit on Man Off Mars. Here is a list of the fixes and add-ons:

• adjusted the mouse sensitivity - it should now be far less sensitive than before;
• worked a bit on sound spread;
• added some new wind effects;
• added environmental objects - rocks and sand storms;
• changed the placement of the end game - brought it a bit nearer to the players most probable location;
• made some other minor adjustments in the game environment and the general feel.
