User should be able to easily find the location of the BQRS file for a query

Currently, in order for a user to find the location of query results files, they must hunt through the logs. The query results view or query history view should include this information (as well as a way to easily open it).

Is the BQRS the most useful thing? I'd expect most users to want a SARIF or CSV export more than a BQRS. (see github/securitylab#164)
