Replace t.delete(:average_title_length) with t[:font_size] = 'xl'

Due to refactoring the hash returned in title_and_context.rb to suit the heading component, average_title_length is no longer passed as an option to ultimately determine the heading size - font_size is used instead. Therefore, in the instances where average_title_length is being removed in some presenters, I've replaced this with setting the font_size.
