Log:
Add line charts for reports

The contributor writes:
I needed a line chart for a custom report and was surprised to find
that it is currently not supported by Gnucash. Line charts are
supported by the GOffice library, so I implemented line charts based
on the bar charts implementation (and added some new parameters for
markers and grid).
