Closes #31

This update speeds up dt_unnest() and makes it generally more predictable. It can also now work with list-column of vectors, although that isn't what it is designed to do. It also keeps all variables, including other list columns.

Thanks to @vincentarelbundock and @kendonB for filling the issue!

Importantly, this now requires data.table v1.13.0 to work (as there was a small bug in the previous version of data.table that won't allow this approach to consistently work.
