Fix ID3::Frame initialization.

[thomas-mcdonald]

When super is called with no arguments all the parameters get passed to the parent object. In the case of Frame < RestrictedOrderedHash this causes an error since its parent does not accept any parameters.

rb(main):008:0> Limestone::Track.new('/Users/tom/Music/iTunes/iTunes Media/Music/Karma Kid/It\'s Always/It\'s Always.mp3')
ArgumentError: wrong number of arguments (7 for 0)

Adding a parenthesis to the call to super causes no parameters to be passed. Not sure if this is due to a recent change in Ruby, not something I've come across before.

thanks Thomas. Yes, the new Ruby Version broke quite a lot.. I'm looking into it.
