Bug 22293: Sticky toolbar making vendor form uneditable

The new floating toolbar plugin doesn't like a particular combination of
markup: A toolbar inside a form which is styled "display:inline." The
staff client CSS styles forms that way globally, so it must be
explicitly overridden in these situations.

Changing the default will have broad consequences, so I propose an
inline style to fix this.

To test, apply the patch and go to Acquisitions. Add or edit a vendor
and confirm that after scrolling down the page the form is still
editable.
