both when a group is specified (no access for others), and without (remove write permissions for group/others);
add stub config parameter for specifying that install dir should be made read-only after installation, and make that changes if the EasyBuild config dictates so

fix making full OpenFOAM installation dir accessible to others (everything readable, dirs executable)

port support for BiSearch and Primer3

hotfix for goalf easyconfig

Why do we create it in the build dir anyway?

add support for DOLFIN

Conflicts:

update README file with contact info + fix links

don't use zlib as dependency for Boost or DOLFIN, this currently breaks the PETSc build (see issue #108); specify 'zlib-devel' as osdependency instead

support multiple sanity check commands, run both Python and C++ version of DOLFIN demos as sanity check commands

only check easyconfig filename against module it provided in resolveDepencies
