Bug 24886: Reindent reports template

Bug 24886: Reindent reports template

This patch reindents the template for saved reports, replacing tabs with
spaces and making indentation consistent. Some lines have been split up.

To test, apply the patch and go to Reports -> Use saved.

 - Test adding, editing, viewing, and running reports
 - Test filtering by group and subgroup
 - Test the process of adding a guided report

 Everything should work as expected.

 Use your preferred method for checking the differences between files
 while ignoring whitespace. I use diff with the  "-w" flag, but I'm not
 your dad. The only changes you see should be split lines.
