Subject: [PATCH] print the current version and build in verbose mode

When specifying the `--verbose` command line option, the application
will now attempt to add the current application version and build number
to the output.  If running from source, it will now print the current
commit.

Having this information will aid in troublehsooting bug tickets going
forward.
