Hello,

I would like to propose a patch for the webbrowser module to actively suppress any output (both on stdout and stderr) from the module itself.

At the moment, doing a quick internet search, the best approximation to obtain this kind of behavior seems to be the ones described in [1] and [2].

In the patch attached I am proposing to add two optional arguments: stdout and stderr to webbroswer.open() (and to the related webbroswer.open_new() and webbroswer.open_new_tab())

Setting stdout and stderr to None effectively suppress any terminal output. The default (True), mimics the current behavior.

There are other minor modifications to clean the code (PEP8).

I will send a similar patch for Python 2.7.X

Cristian
