Sometimes you need a specific break sequence while using word wrap and as today the only option we have is "\n" and is hardcoded.

With this change you will be able to specify any break sequence ("\r\n" for example) as an option.

adding proper documentation for break_sequence in ActionView::Helpers::TextHelper.word_wrap

adding some more documentation for word_wrap custom break sequence and making sure we use new hash syntax
