Merge branch 'master' of github.com:zielmicha/Nimrod
Normalize whitespace in os.nim.

I can't edit it - trick with asking git to ignore whitespace doesn't
work if I need to change indention level.
Add commandLineParams to os.nim.

commandLineParams returns seq of arguments given to program on command line.
Reimplement parseopt which parses arguments given as a sequence of strings, not single string.
