Bug fix release

EDIT: Feb 4, 2016 A small error occurred with the packaging of the release archive. A new source archive has been uploaded, fixing this issue. Please download OpenCoarrays-1.3.2.tar.gz below.

This release addresses the following issues:

• Corrected ftp downloads of prerequisites on Linux.
• Improved the setup.sh file that install.sh creates. Now setup.sh correctly adds gfortran/gcc/g++ and m4 to the PATH and sets LD_LIBRARY_PATH to default to searching for 64-bit libraries with 32-libraries as a second choice.
• SYNC IMAGES now correctly error terminates for image sets containing duplicate image numbers
