generate include.js more frequently

@callahad - mind reviewing?

generate include.js more frequently:
* On every compress
* Every time run_locally.js is called.

Also:
* Build include.js into the resources/static/build directory like other generated resources.
* Rename generate_include.js to create_include.js for consistency
* remove resources/static/include_js/include.js from the .gitignore list
