Installer console

[Wabri]

Need a console installer to set up config.ini something like console_installer.py

1. os detection and request
2. language request
3. request the directory of where yapi must be install
4. request if keep cache
5. request if soft link is need

I would look at the rewrite configuration.py, config.ini, and how yapi.py tests for the config file. You should autodetect the os and then ask if it is correct.
