Change of the location of the configuration files

This version change the location of the configuration files.

For Windows this is now %LOCALAPPDATA%\Skychart and for Linux ~/.skychart

The program configuration is reset to the default values.

After the first run you can copy the files you want to keep to the new folder.

Do NOT copy cartesduciel.ini because it contain invalid file path.
You can then totally remove the folders My Documents\Cartes du Ciel or ~/cartes_du_ciel and ~/.cartesduciel.ini

For Linux the application data directory also change for /usr/share/skychart, if you install additional catalogs you must move them from /usr/share/apps/skychart.


The program documentation make a big start at the initiative of Marceau GUIHARD.
Thanks to the work of all the people who work on the wiki there is now a nearly complete documentation you can directly access from the program.
You can use the Help button or F1 key almost everywhere in the program.
