Subject: added a powerup object that can be placed in levels and represent various powerups... 
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=001cb827d5d08d5f2a47cdd19a72070e314a028a;p=supertux.git

added a powerup object that can be placed in levels and represent various powerups (without the need for a bonus block)
powerups are set according to hirarchy now (i.e. EGG<FIRE<ICE), might need to be changed when we have more powerups; currently this prevents "downgrading" Firetux when he collects an egg

SVN-Revision: 2503
