Planning update

[Dale Liebenberg]

To assist with target planning, I want to add a chart to the target page showing the position of the selected target and moon above the horizon.
I will also add a pop-up with additional information like sun and moon rise and set times.
With this pop-up you can change any of the parameters like date and time, location and even a new target's Ra and Dec.
See the attached example.
Any comments - additional features?
I have done all the (really difficult for a non-mathematician) maths and most of the work, so I can have the update ready by the end of the week-end, subject to your inputs.
