This commit introduces some boilerplate for emitting warnings from the
AbuseFilter parser, and also code for showing these warnings in the ace
editor. Adding new warnings should be as simple as appending to
AbuseFilterParser::warnings (and adding the relevant i18n).

The worker itself is essentially a wrapper around the
abusefilterchecksyntax API.
NOTE: As written in code comments, basically the whole
worker-abusefilter.js script consists of boilerplate code. You can
verify this by diffing this file and 6cb8a9cae1/modules/ace/worker-json.js
This means that there are only ~60 lines of code to review in that file.
