Missing previews for a few system apps

[neilswann80]

@eduardofilo I spotted the preview images are missing for Terminal, System Info and Passwd. Had a little poke around and noticed Simplemenu isn't playing nicely with `.fgl' files.

It seems .png images in the .previews media folder aren't corresponding (as they should) with the .fgl files, instead they appear linked to the exec command in the .fgl itself... weird!

Gets really weird when there is a params line also.

For example for passwd.fgl:
exec=/usr/bin/sudo
params= -S od-passwd-config od

If you rename the image file in previews:
"sudo -S od-passwd-config od.png"

it will actually show the preview! :/

I've raised this weird behavior as an issue with @fgl82 at his Simplemenu repository.
Not really an urgent issue, but I'm really curious as to what's causing it.

EDIT: I've tried using an .fbl to link to an .fgl... even a .fgl to another .fgl, or a .fbl direct to the exec... none worked. :(

Those three launchers are new in 1.4 since SimpleMenu 10.3 supports launching applications with complex callbacks like the one you mention. I was testing and couldn't get the previews to show up. I didn't get as far as you did. I'll take a note for a future version.

While we're on the subject, I've been meaning to ask you how you figured out the mechanism for the fbl's that made it possible to improve Quake's listings.

In all honesty it was just a lot of trial and error experimentation. I think the file extension could be pretty much anything within reason, but I just picked something that didn't seem to already have a purpose and was similar to fgl to make it seem logical to everyone. I knew the fgl files themselves were a special category, but noticed the svm files for SCUMMVM could be used for friendly naming and just played around a bit with the concept.

Definitely a happy accident over any genius on my part!
