ofxNetwork - Check for aborted connections on windows

On windows when a client doesn't disconnect cleanly winsock throws the WSAECONNABORTED error. This provides another way to determine if the connection is gone. This causes a lot of headaches when working with ofxMostPixelsEver.

osx makefile: fix typo, point CFBundleExecutable at the actual exe, and update the display names to reflect just the app name and not its path in the build tree.

With this patch, apps can be run successfully via double click in the Finder (or with `open mydemo.app`), whereas previously it was required to invoke the internal exe directly via command line or other.
