dash_e: fixes #109 and #111

Behaviour of -e has not changed, but can be set by passing True or False
as a parameter multi_dash_e to tox/_config.py: prepare_parse()

This parameter should come from a user specifyable default value
for backwards compatibility. Default should preferable be True after
that is implemented.

_split_env() was factored out of class parseini to enable testing

The issue #111: error on specifying same env twice ("tox -e py27,py27")
fixed. Multiple specifications of the same environment result in
multiple invocation (this could also be selectable in a
configuration file)
