Fix #78

Use alphabetical order in desktop files list, to sort by application name instead of filename.

It feels to me like this would better be solved right in the list-entries function instead of this place, which is really just about mapping specific script parameters to internal functions. IMO we should not add logic in this area.

Is there a reason it cannot be done in the function itself?

Thank you very much
