Form inputs should not have width limitations by default.

Hi there,

I find that these setting are limitations and quite annoying as I'd have to set 'horizontal_label_class' on every form, especially on forms from other vendor bundles I'm too lazy to tweak.

I believe the by default param should be left empty, and for everyone who wants to set it > they should go in the configuration file and tweak it.

Anyway, choice is yours though.

Thanks !
