ZeroClipboard.js is not needed any longer

[luismaia]

Hi,

I just use this gem (version 2.1.10.0.2) in rails (version 4.1.0) and I was getting problems (the buttons of the TableTools extension were doing nothing).

It happened because I was adding:
//= require dataTables/extras/ZeroClipboard
after
//= require dataTables/extras/dataTables.tableTools

It looks like that after this commit (DataTables/TableTools@de627aa#diff-af0ec7aac27919a30348776e1321c59b) is no longer necessary to include ZeroClipboard.js, since it's "duplicated" in the file dataTables.tableTools.js.

For what I understand after TableTools version 2.2.0 (28 Jan 2014) it is only necessary to reference file dataTables.tableTools.js.

Do you agree with ZeroClipboard.js deletion?
If so, I can send you a pull request.

Thank you!

Hi @luismaia, thank you very much.
Please, could you fix the README.md too with a note about this change?
I am waiting your PR.
