Updated Readme

Hi,

I changed a little bit the installation instructions:

• I found them a little bit messy, so re-organized sections
• added a note about not forgetting atoum in composer.json
• I'm not sure the @dev tag exists, so the required version is dev-master
• added a few precisions

Hi. Thx for this PR but few notices :

added a note about not forgetting atoum in composer.json

Why ? atoum is already required in composer.json of the bundle

I'm not sure the @dev tag exists, so the required version is dev-master

@dev is not a tag, it's a stability flag. But you're right, dev-master is correct and works fine. The @dev is required only on atoum/atoum when your minimum-stability is not set as dev

Hi,

I've just checked again, composer complains that you need atoum when trying to install only atoum-bundle.

@romaricdrigon Thank you for this PR.

In composer.json we needs to define atoum too since symfony works (since 2.2) with alpha minimum-stability, but if you replace it by dev, you'll not have to do this. I think it's a good idea do define both on composer.json.

Thank you ;)

De nada, that's a great bundle :)
