Update library size

[robertmassaioli]

Your tagline: "No Flash. No dependencies. Just 2kb gzipped"

Actually:

So it's about five times bigger than advertised. Even gzipped it's too big:

$ wc -c clipboard.min.js.gz 
3257 clipboard.min.js.gz

If this project stops using OO the code size can be shrinked tremendously.

@robertmassaioli Take it easy boy. The code grew and we forgot to update the tagline. As you said, it's 3kb gzipped and I'll update the tagline now.

@FagnerMartinsBrack I'm completely aware about that but I still prefer this approach.

If you guys believe 3kb gzipped is too much, feel free to use another library.
