SimpleHTTPServer does not support POST

[Heliosmaster]

In the section "Adding new comments" we start laying down the structure and the code required to add new comments to the json file though POST requests, and yet the Python module SimpleHTTPServer does not implement POST: in the doc you can see that only do_GET and do_HEAD are implemented.

A solution is to use a custom HTTP server which implements also POST, such as in http://sheep.art.pl/Wiki%20Engine%20in%20Python%20from%20Scratch

or maybe update the tutorial to reflect the implementation in this repository, with node.js.
