When observers subscribe to a property, they are immediately notified
with its status and value if the device exists. Also making sure not to
readd properties to RO sanity check.
It looked like I already had a working solution for KStars INDI vs.
vanilla INDI trees using an #ifdef that is issued by the vanilla INDI
build system. This solution works, if there is a better one, please let
me know.
Simplified the "Day Duration" calculator module. Actually, while the
operation of the module is simplified, its fucntion has been expanded,
it now shows data for the Moon as well as the Sun. I'm planning to
rename this module to "Daily Almanac"
There is now a "Location" button for choosing a place with the Location
Dialog (instead of entering Longitude/Latitude values). As usual, I
removed the Compute and Clear buttons, and changing the input data
(location or date) automatically updates the output fields.
