Dynamically adding reports

This sounds like a useful improvement.

I have a minor comment, which might be a tangent: When using the 
~/.gnucash/config.user to specify "load-from-path" reports, it will not 
work unless the absolute path is specified; e.g. 
"/home/user/.gnucash/reports/myreport.scm". If I use "~/.gnucash/..." 
the report will not load.

This will then allow a user/developer to just drop a new report file into the reports directory, restart gnucash, and it will be picked up.  Or, (get-report-list) could read the list of report file names from a standard-report-names.txt file, which would allow the user/developer to drop a report file into the reports directory, add the file name to the standard-report-names.txt, then restart.  My preference is for the former (fewer steps), but a little more difficult.

I think what I will do is create a 'standard-reports' subdirectory to the reports directory, and put the standard reports (or symlinks) there.  get-report-list will then have a single directory from which to get all of the file names.
