Unavailability in the Leave Demand Chart

Unavailability can now be included in the Demand Chart
 found on the Leave page in Tanda, letting you see the full picture of who can't work:
Temporary changes to availability
 and once-off unavailability
 requests are shown in grey in the chart and can be toggled on or off by ticking 'Show unavailability
'.
Availability changes are converted into periods of unavailability to easily see who can't work and when.
