[WIP] Offliner can handle multiple requests to delete commands

- [x] `[BOT]Offliner` iterates over multiple IDs as parameters for `dl` and `rm` commands
- [x] Addition of multiple magnets to same entry ID
- [x] Entry deletion by VIPs increments deletions count by 2 whereas magnet deletion increments it by 1.
- [x] Active moderators should have deletion count below 11 (previously, it was 6)
