`hy --spy` fails on hy 0.9.11.

This adds real command line handling to 'hyc' for issue #256
This fix catches missing/unreadable files and prints a nice
error message instead of a nasty stack trace when trying to
compile a non-existent file.
Also add this non-existent file check to hy to prevent the
current stack trace from something like "hy foobarbaz" when
"foobarbaz" doesn't exist.
also changes the failure return value to 2 to match Python.
Summary: This update does away with the scripts in bin and changes
setup.py to use entry_points in cmdline.py for the scripts 'hy' and
'hyc'.
This fixes installing and running on Windows.
The tests are updated to run the 'hy' script produced by setup.py
and not from bin/hy. This is more correct and makes the tox tests
run on both Window and *nix.
For running hy or nosetests directly in the source tree, you do have
to run 'python setup.py develop' first. But since tox runs and builds
dists, all tox tests pass on all platforms.
Also, since there is no built-in readline on Windows, the setup.py
only on Windows requires 'pyreadline' as a replacement.
Switched from optparse to argparse in cmdline.py
Instead of trying to manually separate args meant for
hy from args meant for a hy script, this switches from
optparse to argparse for the CLI.
argparse automatically peels out args meant for hy and leaves
the rest, including the user hy script in options.args.
This fixes the issue @paultag found running "hy foo" where
foo is not a real file. Also added a test that makes sure
trying to run a non-existent script exits instead of dropping
the user into the REPL.
Added argparse as setup.py resource (and removed from tox.ini) as well as removed uses of deprecated setf
