Removed classes name suffixes

[benjamindulau]

Hi,

I'm in favor of removing all classes name suffixes in the Acme\Task namespace everywhere it's not inside a Symfony's bundle.

So we would remove "Command", "Event", and so on...

Does it feel weird to keep suffixes in bundles only?
I mean, we don't need them in first-citizen classes, but we obviously need to follow conventions in Symfony related classes. So we'd have mixed naming conventions ;-)

What do you think?
