slightly increase wait time for asyncprocess.recv_some to 0.2s, because unit test was something failing because 0.1s was not long enough for an echo to always finish

redefine semantics for software build options (search only, don't generate); added --try-X options that does make EasyBuild try to generate a matching easyconfig file and use it

add support for SHRiMP

additional python packages: Cython, ASE, GPAW, Theano and CVXOPT

python-meep + deps

remove superfluous script change_toolkit.py, replaced by command line options like --toolkit and --amend

Conflicts:

fix pick_version (avoid crashes when no less recent versions are available); take a deep copy of the specifications passed to select_or_generate_ec such that it doesn't get updated on the caller's end; make match check stricter, also take into account parameters that are not set in selected easyconfig; correct updating of toolkit with specified version; mention old version in comment for tweaked parameter values

h5utils and shapely + deps
