[ticket/4412] Shorten long profile fields

Shorten long profile fields using CSS

This solution makes browser hide part of long words that don't fit container. For example, "http://www.programmersworld.elementfx.com" value from website ticket example becomes "http://www.programmersworld...".

This fix works in all browsers, including IE8.
