Various little improvements

Check ownership and permissions under /files when version update:

https://github.com/bkauler/woofq/commit/dda399b7a1707b7d8d4a2767874d5c45d02c0b09

Update mime-logo for 'easy-*.img' files:

https://github.com/bkauler/woofq/commit/816366b906975f1d39d3f821de03f86a7e6cd369

Create /files/apps/<appname> for all apps that run non-root (not just appimage and flatpak apps):

https://github.com/bkauler/woofq/commit/3ab88767b38d1d0c02c8ce3c7260fd354e3bc9d1

...so all non-root apps will have their own private project folder, hidden from other apps.
