Headlessly install binary.

[kenorb]

The goal is to perform unattended installation of the given binary into given (can be also default) folder.

This can be achieved either by:

• looking into winetricks how it's performing similar installation for other apps,
• using software wrapper or a script,
• using xdotool
• extracting files manually from the installer binary file,
• or any other method which would work (given installation file binary or files which it's downloading),

Acceptance criteria

1. Provision VM: vagrant up.

2. Log-in to VM (vagrant ssh) and run: /vagrant/scripts/install_mt4.sh.

   Or: vagrant ssh -c /vagrant/scripts/install_mt4.sh

After that I'm expecting to see installed files in /opt dir (eventually in ~/.wine folder).

This can either work on mt4setup.exe, itc4setup.exe, mt5setup.exe, itc5setup.exe or any other binary which would provide up-to-date version of the platform binaries.
