First batch of GE API cleanup.

The principle is to replace most get/set methods of logic bricks by direct property access. 
To make porting of game code easier, the properties have usually the same type and use than
the return values/parameters of the get/set methods. 
More details on http://wiki.blender.org/index.php/GameEngineDev/Python_API_Clean_Up

Old methods are still available but will produce deprecation warnings on the console: 

"<method> is deprecated, use the <property> property instead"

You can avoid these messages by turning on the "Ignore deprecation warnings" option in Game menu.

PyDoc is updated to include the new properties and display a deprecation warning
for the get/set methods that are being deprecated.
