Set admin password by container variable?

[mgutt]

I don't know if this would be possible but I like to have the feature to set the admin password through a container variable. By that it would save the step to use the terminal and edit the tinyfilemanager.php file.

It would be possible, but I'm not using tinyfilemanager anymore.
However, I'd take care of any pull requests.
