[Stellarium-pubdevel] renaming of members in the core

[Matthew G. <mat...@gm...>]

Recent changes to use the QT properties system have included the
renaming of many core class member functions.  In the case of public
slots, this directly changes the scripting API.  I also don't think
the replacements offer any real improvement over the previous names
(e.g. getFlagNames vs. isNamesDisplayed).

Please change the names back.
