UD Navy Grunts addon

Nice attempt, but it's better to compile all model in one file, without those *01-04.mdl (it's a legacy of optimization for very slow PCs in 20th century).

When i made these one, where in the concept of the recruit or normal military grunts for residual point hehe, still they were on the secondary plans, and i never fixed the sequencegroup 64 :v.
