More 1.8 support

I realize that both Slikey and NathanWolf are working hard to update this library to 1.8 so I thought I'd help (since I need it for my server). The stack trace from my server seems to indicate that the problem is coming from the ParticleEffect library rather than the actual EffectLib core itself. By updating ParticleEffect from 1.4 (old - 1.7) to 1.6 (new - supports 1.8), I believe that the problems with 1.8 should largely be gone ...
