* Some quick tests for Schema
Simplified output for findRelationshipPath. Always includes start and target in the result.
This simplifies a lot of code in QueryBuilderParser.php
This also always loads the target table data now (which we want)

* Make bill_id the PRIMARY index for the bills table

* Load macros from a json file in misc instead of the database.

* Fix whitespace and wrong key for collection.

* Handle IN properly when generating SQL

* Fix glue (devices.device_id = ports.port_id) is incorrect :D
Show ALL tables we can resolve relationships for in the query builder filter.

* Remove all macros from the database
Remove insert statements, leave updates to update user's existing rules.
