- cleaned some minor code
- use IPv6 if IPv4 isn't available
- add input validations, fixes#86 .
- assign secondary DNS to primary DNS value if it's empty. Fixes#68
- use `$SERVER_WG_IPV4` and `$SERVER_WG_IPV6` when suggesting the client IP
- save user DNS to `params` file and apply it to all clients, removing support for customizing DNS for individual clients. If this is a problem we can add again the code to allow customization but maybe use the sourced DNS as a suggestion for clients that need a different one
- add shellcheck ignores, needed for IDE that have shellcheck support
- escaped variables to `"${var}"` style
- updated README to reflect changes
- fixed the kernel mismatch issue on CentOS by updating the kernel https://github.com/angristan/wireguard-install/issues/95#issuecomment-653696198. Fedora might need this change too
- Use `firewall-cmd` only if `firewalld` is running. Fixes#95
- Fix the client's subnet mask. Fixes#87
- Save the client configuration in the correct `$HOME`. Fixes#96

This commit puts the client creation logic into a function.
By running the script followed by `add_client`, the user will be asked a
few questions and a new peer will be added.
Removing client is **not** supported.
The client files have random names.
Fix for https://github.com/angristan/wireguard-install/issues/3
without resolvconf package, systemd unit file will fail in Debian 10 and ubuntu 18.04 or higher versions
see error below
