IMPORTANT!!! Configuration Makefiles now have a .conf suffix

Until now, the configuration Makefiles (in
`reproduce/software/config/installation' and `reproduce/analysis/config')
had a `.mk' suffix, similar to the workhorse Makefiles. Although they are
indeed Makefiles, but given their nature (to only keep configuration
parameters), it is confusing (especially to early users) for them to also
have a `.mk' (similar to the analysis or software building Makefiles).

To address this issue, with this commit, all the configuration Makefiles
(in those directories) are now given a `.conf' suffix. This is also assumed
for all the files that are loaded.

The configuration (software building) and running of the template have been
checked with this change from scratch, but please report any error that may
not have been noticed.

THIS IS AN IMPORTANT CHANGE AND WILL CAUSE CRASHES OR UNEXPECTED BEHAVIORS
FOR PROJECTS THAT HAVE BRANCHED FROM THIS TEMPLATE. PLEASE CORRECT THE
SUFFIX OF ALL YOUR PROJECT'S CONFIGURATION MAKEFILES (IN THE DIRECTORIES
ABOVE), OTHERWISE THEY AREN'T AUTOMATICALLY LOADED ANYMORE.
