New Towers

• New Tower, Viral tower. Which either radiates the surrounding area and damages those who come into contact with it. Or make the target a biohazard which slowly infects those around it.
• New Tower, Loot tower. This tower increases the looted reward of enemies killed within its sphere of influence.
• New Skill Tree, more tree like and with more skills added along with more modifiers.
• More visual details added to enemies and towers
• Added alternate physics as the original caused performance problems when lots of enemies died at once.
• New level which uses randomly generated levels... wonder how this will work out.

New Enemy Types, and a couple new Tower types are the next thing I'd like added into it, a long with the constant expansion of the levels, hopefully moving onto a new world next.
