Message:

orxonox/trunk: added Shell Class to the utils.
This class should enable us to print all the output from orxonox directly onto the screen.
Also it should allow inputting some little Commands, so that we have more force over our little project

Also added a new Function to tList, removeLast, that is very quick in deleting the last element, as this is used inside of the Shell (deleting the Last Element is a major issue)
