TBoGT Luis's helmet for GTAIV Niko Mod

This MOD replaces Niko's normal motorcycle helmet model to Luis's more heavy-duty motorcycle helmet.

This is not a simple export-from-TBoGT-then-inport-into-IV stuff! Thanks to OpenIV's openFormats feature I can edit the .wdd file without causing any bug. Unlike other export-then-inport kind of MOD your Niko can still wear hats and glasses with this MOD.
