[Rcpp-devel] Additional constructors for DataFrame

Although DataFrame is a subclass of List, it's missing a few handy
constructors that List (i.e., Vector) have, such as "(const int& size)"
to pre-allocate the space for it.
Yes, I can always create a List first and convert it to a DataFrame
afterwards, but this actually doesn't copy some attributes from the
original List. (I noticed it for "row.names", but there may be others.)
I'd be happy to submit a small patch, but wanted to check here first if
I'm missing any potential problems around these constructors and that's
the reason why they are not available for DataFrames.
