titleize 1.2.0

Adds String#titleize for creating properly capitalized titles. It can be called as Titleize.titleize or "a string".titleize. It is also aliased as titlecase. The list of "small words" which are not capped comes from the New York Times Manual of Style, plus 'vs' and 'v'. If loaded in a Rails environment, it modifies Inflector.titleize. Based on TitleCase.pl by John Gruber. http://daringfireball.net/2008/05/title_case
