Provide crash logs

[rquinlivan]

Is your feature request related to a problem? Please describe.

I've been trying to integrate an app image with AppImageLauncher. It works great for many app images, but I am finding issues with integrating one. The problem image is Scrivener. I can launch it by using the "run once" option, but if I click on the icon generated by AppImageLauncher, it hangs for a minute, and nothing happens.

Describe the solution you'd like

I'd like to have crash logs available through AppImageLauncher that allow users to debug why an app image isn't working.

Describe alternatives you've considered

I checked in syslog and didn't find that it was logging anything. If there is a way to get the launcher to log verbosely to syslog or some other log file, that would be a great workaround for me.
