Bug fix release

The installation path naming convention that release 1.7.0 adopted for prerequisite packages now applies to OpenCoarrays itself. An installation line such as

./install.sh --install-prefix /opt/my-stuff

will result in all installed files and directories (.e.g, bin, setup.sh, etc.) being installed directly in /opt/my-stuff without appending the package name (opencoarrays) and version number to the path as happened in previous versions. If no installation prefix is supplied, the package name and version will still be in the default installation path. For example, installing the current version (1.7.1) with no arguments

./install.sh

will still result in an installation in ${OPENCOARRAYS_SRC_DIR}/prerequisites/installations/opencoarrays/1.7.1.
