pepper.cmd wrapper not included in pip package

[LindgrenCarlFredrik]

Steps to reproduce:

1. Setup a venv on windows
2. Activate the virtual environment
3. pip install salt-pepper

Doing this only pepper is available in virtualenv/Scripts and not pepper.cmd
Obviously not critical since the workaround is to just manually copy and insert pepper.cmd in virtualenv/Scripts

Furthermore, cmd can not handle targeting with quotes or backslash.
I.e. pepper "*" test.ping and pepper \* test.ping will not work but pepper * test.ping works.
Maybe this should be mentioned in the docs since I had to debug the HTTP messages to work this out.
