Complete refactor of the code. Basic changes:

1. Split logic into functions.
2. Change location of conf and logs based on root Vs. non-root user.
3. Support installation of script in a standard location (such as /usr/local/bin) and still run it with logs from a standard user. Currently this is not possible as the script searches for the conf file in the script directory.
4. Support of telegram topics.
5. Check command dependencies.
6. Use dig before nslookup for lookups.
7. Add one more service for external IP detection
