moban should report the directory is missing

[jayvdb]

Running moban on an uninitialised pyexcel/pyexcel clone:

OSError: Both pyexcel.yaml and commons/config/pyexcel.yaml does not exist

This is a little confusing.
It would be better to identify that commons doesnt exist.
And per #6 , moban should find it automatically!

Also pyexcel.yml exists, which may cause the user to wonder if that is related to the problem.

[jayvdb]

Likewise if only commons exists, running moban without setupmobans results in:

$ moban

Yep, I will fix it.
