Update MonetDB to Oct2014-SP1 release and add optional packages

Update MonetDB to Oct2014-SP1
Set the correct readline when building.
Add instructions to install GEOS, UnixODBC, GSL, FITS and Sphinx.
Add libatomic_ops as a recommended dependency.
Also add option to enable the R-integration.
Add gettext and libtool for as building dependencies - they are needed for bootstrapping when building the head.
Remove the JAQL reference, removed in MonetDB Oct2014.
The R integration is not enabled by default when MonetDB is built, since it is still experimental. In addition it also requires R to be installed on the system.
Still, there are many MonetDB users who would want to have their installation to work with R, without having to build it form sources themselves.
