an option for the xunit file ?

[agallou]

in https://github.com/agallou/atoum-standard-edition/blob/master/configuration.php#L25 we add an environnement variable to indicate where to writte an xunit report (this could be usefull in ci environnements)

Should we add also an option (like a --log-junit <file> for example) ?
(and also, should the presence of the option override the envionnement variable configuration (if the env is present and the option is passed, only the option is used) ? (I think it should)

cc @jubianchi, @Grummfy ?

in this case it should be the same on other options. I would prefer to have a command that list the env var available

[agallou]

@Grummfy the PR #15 lists available env vars.

nice

So,
what we will do about this one?
