fix css - container-inline

I was having a similar problem where form labels were imposing their block display even though they were in the container-inline element.

This patch targets both divs and labels so that labeled form elements will appear inline as well. It also moves the .container-inline declaration down to the bottom of the CSS so that it won't succeeded by the ".form-element label" declaration.

Here's an illustration of inline form elements after this patch has been applied.

This issue probably requires some discussion. I'm changing the priority though because it isn't really critical.

.container-inline div is now defined in modules modules/system/system.css

.container-inline div {
  display: inline;
}

.form-text is now defined in modules/node/node.css

.node-form .form-text {
  display: block;
  width: 95%;
}

The first patch suggests:

.container-inline .form-text {
  display: inline;
  width: auto;
}

The second patch only changes:

.container-inline div, .container-inline label {
  display: inline;
}

Not sure if this is to be marked fixed but IMO this is not a bug.
Left Category and Status to be changed by next reviewer.

I merged the two patches. The fix is to have .container-inline nullify only the exact items which we change (node form text fields, non-option labels, ...).
