scripts doesn't work directly on windows

[JayXon]

λ hachoir-metadata
'hachoir-metadata' is not recognized as an internal or external command,
operable program or batch file.

but it's in PATH

λ which hachoir-metadata
/c/Users/JayXon/AppData/Local/Programs/Python/Python36/Scripts/hachoir-metadata

I have to do this:

λ python C:/Users/JayXon/AppData/Local/Programs/Python/Python36/Scripts/hachoir-metadata
Usage: hachoir-metadata [options] files

Options:
  -h, --help            show this help message and exit
  --type                Only display file type (description)
  --mime                Only display MIME type
  --level=LEVEL         Quantity of information to display from 1 to 9 (9 is
                        the maximum)
  --raw                 Raw output
  --bench               Run benchmark
  --force-parser=FORCE_PARSER
                        List all parsers then exit
  --parser-list         List all parsers then exit
  --profiler            Run profiler
  --version             Display version and exit
  --quality=QUALITY     Information quality (0.0=fastest, 1.0=best, and
                        default is 0.5)
  --maxlen=MAXLEN       Maximum string length in characters, 0 means unlimited
                        (default: 300)
  --verbose             Verbose mode
  --debug               Debug mode

I think the reason is that windows doesn't support #! in script, you might have to create a batch script for this to work.
For example a hachoir-metadata.bat file in the same directory with hachoir-metadata with something like this works for me.

@python %~dp0hachoir-metadata

Or a hachoir-metadata.bat file like this which doesn't need hachoir-metadata script.

@python -c __import__('hachoir.metadata.main').metadata.main.main()

Sounds like a good idea - do you want to make a PR adding these batch files?

You can use python3 -m hachoir.metadata. I don't know if you can type python3 or python3.6 on Windows. Maybe you can use py -3 -m hachoir.metadata.

[JayXon]

python3 or python3.6 won't work, but since I only have python 3.6 installed, these 3 all works:
python -m hachoir.metadata
py -m hachoir.metadata
py -3 -m hachoir.metadata

Anyway, I did a little bit of research and it seems you should be using entry_points instead of scripts in setup.py, so that setuptools will handle cross-platform compatibility for you. I could come up with a PR if this sounds good to you.

Using entry points was my long term plan. That's why I moved script content into hachoir/ directory and simplified scripts to 3 lines.
