Render numeric axes in charts as Integers
When rendering charts in the issue reports and repository statistics, chart.js will render the axes with fractional numbers if there are only few entries. However, as the number of issues or commits are always entire integers, this is rather confusing and pointless.
The attached patch against the current trunk at r22135 fixes the rendering of the respective axes of chart.js charts to always use full integers. The patch was extracted from Planio.
