Big refactorHEADmain

TL;DR: this commit makes README.md more simple and makes scripts more
complex.

This commit makes scripts look (and behave) like scripts.
That is, they now contain shebangs, `echo` lines to allow user
to watch the installation process. The latter is now more configurable:
user can customize the directory, where LibreTranslate will be installed,
username, which will be used to run LibreTranslate and the domain name
configuration is now contained in the .env file, which used for all
other settings.
