Functional intelligence framework.

- All 5 intelligence tests pass.
- Some initial memory optimizations done.
  - More work needs done to reduce duplicate data in memory.
- Input framework integration.
  - Define files to read in the "Bro intelligence format" in Intel::read_files.
- Cluster transparency.
- DNS Zones are a fully supported data type.
  - Queries for Intel::DOMAIN values will automatically check in DNS_ZONE intelligence.
