Properly adjusted the location of ANIMO's configuration file inside the
CytoscapeConfiguration directory. Also, greatly improved the verifyta
search: first we try to find it ourselves looking in the user directory
and possibly in all other available disks. If we succeed, we don't ask
the user to look for it themselves, but just show the one we found. The
request to the user is done only as a second attempt, in case we find no
verifyta executable.
Of course, because we just look for a file named "verifyta" (linux and
mac) or "verifyta.exe" (windows), even when finding it the chances are
still not-0 that we didn't actually find the file we were looking for..
