Published menu to prepare RosBE on Linux

[SSantos]

Hi all,

because I had a lot of problems to set up RosBE on Debian Testing I started a bash menu to easily set up a RosBE envionment via Docker and to download and integrate optional modules. It is available on https://github.com/SantosSi/RosBE-Manager. Please check it out and comment, suggest improvements or develop them yourself.

FYI:
First added optional modules, like downloading Gecko or AC97 sound drivers, to integrate into images.
Then added a function to search for resource files not translated into a selected language.
