Sharing files makes bad request (nim 0.19.0, win64, gcc 6.3.0), I don't know why.
Hello!
I have this:
gcc (x86_64-win32-seh-rev1, Built by MinGW-W64 project) 6.3.0 as suggested,
Nim Compiler Version 0.19.0 [Windows: amd64]

I installed jester via nimble. Normal stuff like serving text works like a charm. But sharing files do not.
I'm not able to get public folder to work. I'm not sure if it's my fail and hope you don't roast me to much ;-)
Here is a log if that of any help:
```

C:\Users\x\Desktop\webtest>type hello.nim
import htmlgen
import jester

routes:
  get "/":
    resp h1("hello world")
  get "/test":
    resp a(href="movie/DVD571_05.mp4", "gogo")
  get "/test2":
    resp a(href="hm.html", "click for hm")
Then, if I try to > http://localhost:5000/movie/DVD571_05.mp4 or http://localhost:5000/hm.html I get:

C:\Users\x\Desktop\webtest>hello
