DataTables 1.10.2

It is basically done now. The changes in parseQueryString() may look evil, but I do not have a more elegant solution.

Shiny gallery examples have been updated in the repo but not on the website yet (should be there after shiny 0.10.2 is released): https://github.com/rstudio/shiny-examples/commit/6f2a5618d12b0ea62437aa88188ac5531bc7dc35

There are more examples to work on to explore the new features of DT 1.10.
