New issue 331: Output with missing setup.py could be nicer
https://bitbucket.org/hpk42/tox/issues/331/output-with-missing-setuppy-could-be-nicer

Florian Bruhin:

When there's no `setup.py`, we get:

```
$ tox 
Traceback (most recent call last):
  File "./.venv/bin/tox", line 11, in <module>
    sys.exit(cmdline())
  File "/home/florian/tmp/.venv/lib/python3.4/site-packages/tox/session.py", line 39, in main
    retcode = Session(config).runcommand()
  File "/home/florian/tmp/.venv/lib/python3.4/site-packages/tox/session.py", line 375, in runcommand
    return self.subcommand_test()
  File "/home/florian/tmp/.venv/lib/python3.4/site-packages/tox/session.py", line 520, in subcommand_test
    path = self.get_installpkg_path()
  File "/home/florian/tmp/.venv/lib/python3.4/site-packages/tox/session.py", line 496, in get_installpkg_path
    path = self._makesdist()
  File "/home/florian/tmp/.venv/lib/python3.4/site-packages/tox/session.py", line 390, in _makesdist
    raise tox.exception.MissingFile(setup)
tox.MissingFile: MissingFile: /home/florian/tmp/setup.py
```

instead the output could be nicer, like if the `setup.py` is broken:


```
$ tox                               
GLOB sdist-make: /home/florian/tmp/setup.py
ERROR: No dist directory found. Please check setup.py, e.g with:
     python setup.py sdist
```
