fixes in Pasha and tbb + apply patch for recent libstdc++ with intel compilers aswell (closes issue #142)

hotfix for goalf easyconfig

Why do we create it in the build dir anyway?

add support for DOLFIN

Conflicts:
	easybuild/build.py

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

fix easyblock specification in easyconfig files according to new class name encoding scheme (see #86)

add support for creating a dependency graph based on easyconfig files

Conflicts:
	easybuild/tools/filetools.py

86 encoding scheme
