Title: use std::regex if it is available

it turns out that boost::regex does not work for the libstdc++ debug
mode. This patch should fix this for sufficiently new compilers.

Note that this requires the FindCXX11Features.cmake tests pulled in
from opm-core and an additional compiler flag...

please hold off from merging this until the other modules have merged their respective PR...
