Use error-reporter

This depends on:
- [ ] the-gss/preparser#4
- [ ] the-gss/ccss-compiler#14
- [ ] the-gss/vfl-compiler#6 (~~which depends on the-gss/vfl-compiler#7~~)
- [ ] the-gss/vgl-compiler#5

I've linked all of those dependencies locally using `npm link` in order to work on this. The build status of this pull request is irrelevant until those are merged or I point to the relevant branches in `component.json`.

@d4tocchini - could you provide examples of statements that will generate the following errors?
- ~~VGL generated VFL parse error~~
- ~~VGL generated CCSS parse error~~
- [x] VFL generated CCSS parse error
