Fixes #290: pyPrint accepts any filelike, with sys.stdout fallback

[alanjds]

Gets sys.stdout from SysmoduleDict['stdout'], that exists and could be replaced (after #146 got merged)

pyPrint allows any filelike *Object to be printed to.

TBD: Factor out the method invocation logic to some func (o *Object) Invoke(f *Frame, method *Str)

Have no idea why this is broke. Halp.

Left is OSX. Right is Linux

The types_test failure is because types.py defines ModuleType as type(sys) and types_test checks that it's the same type as go.grumpy.ModuleType. sys is now a different kind of object.

I would remove that line from types.py and add from __go__.grumpy import ModuleType to the top of that file.

The other issue is a transient failure due to a race condition in TestRunMain. I can trigger it reasonably consistently as follows:

$ GOPATH=$PWD/build go test grumpy -test.run=TestRunMain -count=100
--- FAIL: TestRunMain (0.00s)
	module_test.go:300: runMainRedirectStderr() failed: read |0: bad file descriptor
	module_test.go:300: runMainRedirectStderr() failed: read |0: bad file descriptor
	module_test.go:300: runMainRedirectStderr() failed: read |0: bad file descriptor
	module_test.go:300: runMainRedirectStderr() failed: read |0: bad file descriptor
FAIL
FAIL	grumpy	0.047s

I think this is similar to google#282. This is not due to your change. Just restart the build if you encounter that again.

OSX: Thanks. Will take a look on types.py. I had used the import errno; type(errno) on the "hack module" as errno is a so simpler module. Is this acceptable for you?

Linux: Good to know. However, how can I restart the build on Travis? Last time I had sent a pointless commit to trigger it, but this adds noise to the history.

I had hit another strange error here, on itertools_test.py:

NameError: name '__name__' is not defined
exit status 1

Bisected and found its root on f745cdb, but it makes no sense.

As this PR will not be merged until __getattr__ is working, will leave it as is. This seems as a symptom of another undiscovered bug on the module/types stuff.
