Merge pull request #3 from jessek/patch-1

Update INSTALL
Updated to RDS 2.41m, and revised the denistify script to better handle the increasingly large RDS data sets.
Removed the std::set.  Now everything gets stored in a single contiguous block of memory over a gig in size.  This should help deal with memory fragmentation.
Just modifying some READMEs and tweaking the configure.ac to reflect we're now on a 1.2 branch.
Tweaked the configure script a slight bit -- no great shakes.
    Update to NIST RDS 2.42 + drop IPv6 fetch

    Update of the URL to NIST RDS 2.40 and
    IPv4 is forced for wget and curl as the NIST website resolves
    in IPv6 but it's not reachable.
