update lulu splash

and lulu's ingame model face also needs fixing because she looks ugly in compare with poppy & tristana, i wonder how that model even made it to live i would feel ashamed if i was involved in its design

Lulu's base model and older skins desperately need an upgrade... Her SG skin is like so much different it's like two different characters rather than one champ in a different skin. [sg-lulu]

Her splashart is actually pretty good imo.

I think she needs a VU which might include a new splash cause she looks trash in game.
