Adding bin/ directory.  This will house sshm script that can be run from console.
Moved bin/sshm into sshm/sshm.py as main().  Added console_scripts "sshm".  After installing sshm, you can now run main() from console simply by running "sshm"!
Readding bin/ directory to .gitignore.
Added attempt to run console sshm to travis config.
Created seperate arg getters for optparse and argparse.
