Python default logging isn't being output to the console #37

This covers LightTable/LightTable#712. The original comment [bold added by me for the relevant portions]:

Couple things on python's console output:

• I get a lot of "execing" "execed" and "evaling" when running python scripts that belong to LT and not my script (I assume they were part of your debugging output).
• The second point is logging. The logging output is not being shown on the LT console (unless I write to the logger on the same file).

Essentially, the output from evaling the code inside LT compared to doing "python foo.py" is very different and most importantly, it's missing all the debugging output from my own code.
