Enhancement: Move the cached image location

[DarkCoder28]

I have been using this program for a few days now, and I really like it... my one big problem is that I use Nextcloud to sync my documents folder to my personal cloud and it keeps having to reupload the cover image, slowing down my internet speeds and adding unnecessary load to my server. I already had this problem with Rainmeter itself, but was able to change it's library directory away from the documents folder.

It would be great if you either changed the image cache location to somewhere like the temp directory or made some form of configuration for where to store it. Just a suggestion, but I would greatly appreciate it.
