fixed bug in checking output of xtc_CsameF77 tools (need to ignore first two lines of output)

change CP2K and dependencies easyconfigs for ictce (use 3.2.2.u3 instead of 4.0.6, because the latter version uses ifort 2011.6 which has problems, cfr http://software.intel.com/en-us/articles/build-cp2k-using-intel-fortran-compiler-professional-edition/)

add version check for Intel compilers, add extra make instructions for Intel v12 more recent than 2011.8 (cfr http://software.intel.com/en-us/articles/build-cp2k-using-intel-fortran-compiler-professional-edition/)

move "built with" comment to the end of the module file, otherwise the module "shebang" gets screwed up

improve documentation, add comment line that specifies which EasyBuild version was used in generated module file
