Big Number Chart should have an option to display chart title in dashboard

[cccs-jc]

Is your feature request related to a problem? Please describe.
Most of the time it's okay to have a chart title in the dashboard. However for the Big Number chart this makes less sense.

Describe the solution you'd like
It would be great to have a option to remove the chart title in the dashboard. Perhaps this should be an option for any chart placed inside the dashboard.

Describe alternatives you've considered
We can circumvent this issue by naming the Big Number chart ' ' (use spaces to name the chart). But that's obviously a hack!
