Renaming .appimage.home and .appimage.config with update
Background:
When I use an appimage, I usually keep a <appimage filename>.home and <appimage filename>.config directory beside it so that files created by that appimage doesn't get into my user home directory and they're more controllable this way. This works for me so well and it has worked for every appimage I tried so far.
e.g.

When the update completes, the new file is created, but the directories have the same name as before.

Steps to reproduce:
- Download an old appimage (for example this one)
- Create directories named
<appimage filename>.homeand<appimage filename>.configbeside it - Launch AppimageUpdate and show the appimage so that it can update
Current behavior:
Keeps the .home and .config directory names as is, does not update the names according to the new version updated.
Expected behavior:
Rename the .home and .config directories to reflect the latest version downloaded. If it is too direct, maybe a Yes-No message box can ask if the names should be updated.

Some users like to keep these directories per-version, so that the settings of a newer application version don't change/damage the settings of the older application version.
I think it is reasonable for the user to rename them if needed.
