Integrate regex.list items into blocklists using ABP-style domains

[rpakishore]

Pihole now support ABP-style requests

We can eliminate the need for manual regex entries by directly including them in the block lists.

Example: (^|\.)lgsmartad\.com from regex.list can be replaced by ||lgsmartad.com^ in blocklist.

Please let me know if I can create a PR to address this issue.
