consider using red squiggly or other indicator for invalid forms

[bill]

Current exclamation mark icon for invalid form fields is bad since it leaves a blank area to the right of the input, and maybe other reasons (other please update this description)

Consider changing to a red squiggly underneath the form field or have the icon appear inside the borders of the input box like on facebook (IIRC).

This will fix #4489.

(In [10663]) 1. Move validation icon to appear inside the box (for TextBox?, ValidationTextBox?, ComboBox?, and Spinner template based widgets).

2. Width setting applies to outer node: setting combobox to width=100px leaves 16px

for the arrow icon and 84px for the input node (unless the error icon is shown, in which case the input gets less space). Size property desupported.

This is still rough; it needs some more CSS cleanup and haven't even looked at soria yet... but the basics are there.
