Suggestion: do not delete appimage upon remove

[ronenrozner]

When removing an app it will also delete the original appimage file. Perhaps a better behavior (or maybe a preference option) will be to rename the appimage file back to it's original name without the "gearlever" prefix.

Hi, since a few weeks, if you are using a distribution that supports trashing (aka most of them), the old appimage files are not deleted but trashed.

Let me know if that's a good solution for you.
