FIXED: lineBreakMode set to CPLineBreakByTruncating* was trimming consecutive white spaces

Previously, using a truncating line break mode on a CPTextField and setting the string value to "test      test" was displaying "test test". This patch changes the css white-space property from "nowrap" to "pre" which preserves the white spaces.
