Add support for queries, includes, and excludes flags for codegen (#733)

* Add support for queries, includes, and excludes flags for codegen

After the overhaul, support for the queries flag in codegen was altered.
Restore previous behavior and add includes and excludes flags.

Note: excludes patterns don't work in watch mode due to a limitation with
Gaze, the filewatcher we're using.

* Remove unused imports
