Query commenting in Query Workbench (usability)

Summary: Commenting in the query workbench causes the syntax highlighting to change, but a query with comments in it will cause an error.

Repro:

1. Open Query Builder
2. Enter a valid query and some comments. (example:
   1. – this is a comment
   2. SELECT * FROM `travel-sample` LIMIT 10;
3. Click execute

Expected:

The comment to be ignored and the un-commented query to execute.

Actual:

Error message: syntax error

Notes:

In the 5.5 release, using "–" for commenting doesn't seem to affect the syntax highlighting anymore. Still, "–" or "#" is widely expected by SQL users to function as a comment, as I have observed giving a N1QL demo to 200-300 people at recent conferences.
