[WIP] Rename SalesBundle to OrderBundle

[jjanvier]

To fix #378

Is there something else to do ? Maybe something about the subtree split ?
Except documentation of course

[pjedrzejewski]

I added repository, the subtree-split part is on me. Only thing left is the docs PR. Thanks Julien! 👍

[jjanvier]

@pjedrzejewski I'll rebase when you'll be ready to merge this.

[pjedrzejewski]

@jjanvier Please rebase. :)

[jjanvier]

@pjedrzejewski done

[stloyd]

@jjanvier You need to change this: https://github.com/Sylius/Sylius/blob/master/src/Sylius/Bundle/CoreBundle/DependencyInjection/SyliusCoreExtension.php#L82 otherwise it will not work.

[jjanvier]

A few PR have been merged after this one. And a few references to SalesBundle still exist. I'll correct this after lunch ;)

[jjanvier]

@stloyd @pjedrzejewski it should be ok now. I've fixed the glitches and squashed last ugly commits.

[stloyd]

@jjanvier Can you rebase? So I can merge it! Thanks =)

[jjanvier]

@stloyd done, but let's wait for Travis ;)

[jjanvier]

@stloyd greeeeeeeen

[stloyd]

Merged! But tree-split will be available when @pjedrzejewski turn back from Symfony Camp UA =)
