rename Pasha easyconfig dir, added patch file required for ictce, add easyconfig for goalf (refs #1127)

Support for building/installing FSL

Conflicts:
	easybuild/build.py

add support for specifying directory to apply patch in (required for e.g. OpenFOAM)

clean up recursively determining dependencies, fix bug when depth was set to 0 (which resulted in infinite recursion)

only prepare for direct member module of a toolkit , not for implicit dependencies (like icc/ifort for imkl);
add BLACS as explicit dependency for goalf toolkit in example easyconfig

re-add import required for VERBOSE_VERSION, ignore PyDev warning on use of FileRepository in EasyBuild config (config is exec'ed, so it works)

add support for specifying directory to apply patch in (required for e.g. OpenFOAM)
