Manage/Config from a external config file (read)

Purposes/Objectives:
avoid the need of editing the script file.
make easier for user without programming knowledge
allow to move the configuration to a new version of the menu
allow the sharing of a common config file between multiplatform Menu (Win and Mac/*nix)

At the moment the Bash version supports the usage of a config file :)

However:
menu for windows doesn't support this feature yet (batch)
config file is loaded instead of read the content (bash)
loading/call is less secure(bash)
load for windows will require a text, as variables are set differently(batch)
