Provide --ask CLI option
There should be an option to run exo-open, forcing it to open the application chooser dialog rather than simply using the default application.
In effect, this would be turn into exo-open into an "Open with ..." rather than an "Open" command.
As an example of a (CLI) program that already provides such an option https://github.com/mbeijen/File-MimeInfo/blob/master/mimeopen.
Use cases:
- Shell scripting: I want to create an interactive shell script that takes a file parameter and opens it in the program of my choice. Currently the only way to do this is using XFCE tools is to run Thunar with the file as parameter, right click, and open with.
- Code duplication: Currently, xfce-settings and thunar have separate codebases for their nearly identical application chooser dialogs. Providing this option here would allow those programs to call exo-open instead, thus merging this redundant code.
