Minor Tweaks

[GrahamCampbell]

Whitespace and travis.

@sebastianbergmann @GrahamCampbell Just to be clear, why are these changes needed for the composer command?

[GrahamCampbell]

They make sure composer is running at the latest version, then they make sure composer doesn't ask for user input during an install, which would result in travis hanging until build timeout which is something like 40 mins.

[whatthejeff]

@GrahamCampbell Do we have an example where this has been a problem?

Also, isn't --dev on by default?

[GrahamCampbell]

Yes it is, but it's nice to be explicit, even though it is not really necessary.

[whatthejeff]

@GrahamCampbell @sebastianbergmann I don't really see much value in adding extra commands/options when (as far as I know) we've never had an issue with the current command in any of the PHPUnit projects.

Also, we might actually want to enable travis for this project @sebastianbergmann :P
