OpenFOAM 2.3.0 + bug fixes

I took the PR from @tloizou (https://github.com/hpcugent/easybuild-easyconfigs/pull/999) and adapted it to work on top of https://github.com/hpcugent/easybuild-easyconfigs/pull/957.

The change (regarding PR https://github.com/hpcugent/easybuild-easyconfigs/pull/957) is the addition of a new OpenFOAM-2.3.0-goolf-1.4.10-bugfix1.eb file that includes an additional (and non-official) bugfix.
