Add gstack script
This commit adds a '-v' or '--version' option to the existing gcore
script. This new option causes the script to print its version
number, and then exit.
I needed to adjust the getopts handling a little in order to support
the long form '--version' argument, but as this makes gcore more
consistent with gstack, then this seems like a good thing.
The usage message is now getting a little long. Don't worry, I plan
to clean that up in the next commit.
