Improve Python and Linenoise

Browse source 
This change reinvents all the GNU Readline features I discovered that I
couldn't live without, e.g. UTF-8, CTRL-R search and CTRL-Y yanking. It
now feels just as good in terms of user interface from the subconscious
workflow perspective. It's real nice to finally have an embeddable line
reader that's actually good with a 30 kb footprint and a bsd-2 license.

This change adds a directory to the examples folder, explaining how the
new Python compiler may be used.  Some of the bugs with Python binaries
have been addressed but overall it's still a work in progress.
