Subject: * Menu.cpp: actions for CHOICE_SINGLE_PLAYER_GAME have been moved to
 a new function called MainMenuSinglePlayer(). + BaseUnit.cpp, BaseUnit.h: new
 _selected flag. + Camera.cpp, Camera.h: linear movement has been taken over
 quadratic movement. Also, cursor now moves if dealing with screen borders. +
 Cursor.cpp, Cursor.h: new Cursor class holds cursor X/Y information. It is
 meant to be contained inside a HumanPlayer object. * Game.cpp: minor changes
 in casts and comments. + HumanPlayer.cpp: added callbacks for button release
 events. * HumanPlayer.cpp, HumanPlayerBtn.cpp: button handling has been
 transferred from HumanPlayer.cpp to HumanPlayerBtn.cpp in order to improve
 modularity. + Sprite.cpp: sprite data was not being checked against NULL. -
 Unit.cpp: drawHandler() is now executed by Player object.
