Static FileServer

[lxfontes]

discussion #35

Usage

mux.FileServer("/css", http.Dir("./static/css"))
mux.FileServer("/", http.Dir("./static"))

Unfortunately it won't respect chi's NotFoundHandler

thanks @lxfontes for this! I'm going to merge and make a small addition.. that is to remove the _static folder and just use a in-memory http.FileSystem fixture in the mux_test

Was this feature removed in last release (i.e. 3.3.2)?
I am asking this because I have compilation errors when I use it:

import (
	...
	"github.com/go-chi/chi"
)
...
func Start() {
	chi.NewRouter().FileServer("/static", http.Dir("frontend"))
}

compilation error:

src/core/coreModule.go:56:18: chi.NewRouter().FileServer undefined (type *chi.Mux has no field or method FileServer)

Am I doing something wrong?
I see that this is deprecated in 3.0 changelog, it is completely removed now?
