v1.0.0-rc3

Read the commits list for detailed information: https://github.com/gustavo-iniguez-goya/opensnitch/commits/main

Changes:

• UI: display an alert when the user does not respond to a prompt dialog.
• UI: centralized configuration under ~/.config/opensnitch/settings.conf.
• UI: Fixed regex patterns.
• UI: Fixed Allow/Deny second-level domains (github.com, imgur.com ...).
• daemon: Do not panic if we can't parse a regex type rule.
• daemon: if debugfs is not present, parse /proc directly. This allows us to keep functioning on some environments (secure boot on, latest kernels with debugfs unmounted by default, etc).
• daemon: fixed and improved netlink connections querying.
• daemon: improved PIDs cache searching by prioritize PIDs with active connections.
• daemon: improved /proc PIDs searching, sorting by latest modified PIDs.

Note about the deb UI packages:
They're experimental, in the sense that we're trying to make them as much Debian compliant and backward compatible as we can, so expect changes between releases. You may need to remove and reinstall it. All in all it should work in most cases, if not, report it.

Installation:
sudo dpkg -i *opensnitch*deb; sudo apt -f install
