Bug 14013 - Use name of a saved report as part of the file name for download

This patch propoeses the name of a saved report as part of the download file name.

To test:

- Apply patch
- Got to Home > Reports > Guided reports wizard > Saved reports (or create a new report from sql)
- Run a saved report
- Download the report (as csv, tab, ods)
Result: The downlaod file name proposed should be prepended by the report name, separated with a -

- Bonus test: Try to downlaod saved reports which have special character in their name.

NOTE: Used "ñ/â is N/A" as a report name. The /'s were translated
      to underscored, but the letters were as expected.
