Fix gef-extras directory location

[hoefler02]

Better location for gef-extras

Description/Motivation/Screenshots

Moves the ~/gef-extras folder to ~/.config/gef-extras if it exists, or to ~/.gef-extras otherwise. This will help de-clutter the home folder. The gef installer already does this but the gef-extras installer does not.

How Has This Been Tested?

I ran several tests with different $HOME values to verify that the installer still works.

This looks fine to me. Can you change the script to not confusingly (imo) set or not set DIR and name in the if else chain? don't get clever, just fully set the base path in that chain and use a single var in all the invocations

Yes! Thanks for the suggestion! Not sure why I didn't it that way in the first place 😊

You forgot to remove $NAME usage. Please make sure to re-test

My bad! Fixed and retested with different $HOME values and it is working now. Sorry about that
