Use of "anyNA" function breaks compatibility with R < 3.1

Hi,

I have been having troubles installing memisc from sources on a system where I am stuck with R version 3.0.2 (2013-09-25). It seems that the usage of anyNA, introduced with commit [https://github.com/melff/memisc/commit/dd3da28045220e5b3726cfc0f1b56cdaeda87b0c] in function [.mtable breaks compatibility with R versions < 3.1.

I therefore suggest that the R dependency in DESCRIPTION is bumped up to 3.1.

The same issue arose in package curl, see:
jeroen/curl#34

An alternative, used in curl, seems to be to replace usage of anyNA(x) with any(is.na(x)).

Thanks for the bug report. Fixed in release 0.99.4.1
