Make shellscripts runnable from the file manager

[fsimonis]

It would be nice to be able to run a solver directly from the file manager.

An option "Run script" would be useful.

I see your point: it would be convenient to not have to always start a terminal and then start the script. I know that .desktop files can do this, but I would not like to inject and maintain such files.

Do you have any other way in mind?
