Refactor script (#92)

- 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

It will install WireGuard (kernel module and tools) on the server, configure it, create a systemd service and a client configuration file.
To generate more client files, run the following:
```sh
./wireguard-install.sh add-client
```
Make sure you choose different IPs for you clients.
Contributions are welcome!
