Jooboo v0.2

I've made a number of additions and improvements since the last alpha release:

• Added new level
• Jooboo now has a new special weapon: a horn.  When he honks it, all nearby enemies are knocked back.  A good way to get out of trouble!
• Added a roundhouse kick ninja

Note that with the addition of the horn, I have created a way to cycle through the different special weapons that Jooboo is carrying.  Right now, there are just two, the seltzer bottle and horn, but more are coming.  To cycle through, use the + key on the keypad.

Updated controls:

Movement:   ASDW

Jump: Space

Melee attack: keypad 1

Ranged attack: keypad 2

Special attack: keypad 3

Switch special attack: keypad +

Feedback much appreciated!
