Made library buildable for windows.

Modifications:
- made symnlinks hardlinks cause
  git-for-windows/git#117
- made smallest random generated type in tests short because msvc's random lib doesnt support chars
- updated some cmake stuff
- Used the aaa rule to not assume the iterator type in commandhandler
