Improve and fix a couple things in inlineEditor.
This adds a 'title' attribute to the "required" asterisk that says "This

field is required."
It also fixes a bug with setting the width of the editor when the

content wraps. We were previously setting min-width, and I believe this

was from before we properly fixed all the width calculations (to ensure

we had a minimum, and didn't have it shrink unintentionally). Removing

the min-width setting doesn't seem to negatively impact any cases where

we've used an inlineEditor.

Hovered over an asterisk and saw the tooltip.
Tested every inlineEditor I could find, with different sizes and with/without

OK/Cancel buttons enabled, and didn't see any breakages.
