pydarts v0.9 feature freeze

We have been really excited working on this new version of pydarts. With a major code refactoring (yes, again), and many bugs corrected, this version will be the more stable ever went out.

pydarts is now python 3 ready, which means that the project will exists when python 2 (the prog language used for pydarts) will be deprecated. Important for me, at least, and for everybody which is concerned by trying to keep this project alive as long as possible.

The big part is that network handling is now fully included in the game menus. No need for network assistant nor command line anymore (except if you want to run your own server)
At the same time, all the menus has been refactored.

Another important thing is that before each release, everything will be tested on the latest version of Windows. That means actually Windows 7&10, with python 2.7 installed.

The network layer is now really more reliable. It has been tested with success, backup turn works, it is fast and works great.

Config file is now more flexible. No need for all options. The serialport and the SectionKeys are now the only options required. But you may use it to freeze some of your favorite options, obviously.
You may select an alternate config file via CLI using "--config=" option, by the way.
