Support CREATE TRIGGER

Hi,
When I write some trigger for sqlite3, I got following error message:
`Expected "--", "/*", "INDEX", "TYPE", or [ \t\n\r] but "T" found.`

Would you support for CREATE TRIGGER feature?
e.g.

```sql
CREATE TRIGGER updated_at_table UPDATE OF title ON my_table
BEGIN
    UPDATE my_table SET updated_at=CURRENT_TIMESTAMP WHERE id=New.id;
END;
```

Thanks
