can not integrate properly when the icon or desktop file inside AppImage is symlink

[ksharindam]

Hi Prateek,
This is a great intuitive app.
But I have found some bug.
If the icon or desktop file in the AppImage is a symlink, the AppImagePool program copies the symlink file while doing desktop integration. So, the either the icon is not shown, or the application does not show up in Applications Menu (example apps - PhotoQuick, Firefox Nightly).
Instead, it should follow the symlink, and copy the actual icon and desktop file from the AppImage.
