BUG: 232162
FIXED-IN: 5.12.3

Differential Revision: https://phabricator.kde.org/D25266

this addresses https://bugs.kde.org/show_bug.cgi?id=411608
which refers to a much older KOrganizer version 5.9.2.

Newer KOrganizer handles grid color (computed from the
windowtext) just fine when using system settings; but,
not when using customer background colors.  With this
patch we fix that.

The bug report requested a custom configuration for the
grid color.  The UX team doesn't want that and requested
to remove the ability for custom colors completely.
That's a different thread and a different fight.

They may influence other imports - in particular, ECMGeneratePriFile uses KDE_INSTALL_USE_QT_SYS_PATH, which is initialized in KDEInstallDirs, to determine the mkspecs install dir

Summary:
This fixes the broken connects due to the KCalCore->KCalendarCore
renaming, which fixes clicking on dates in korganizer.

Test Plan: I can select dates in korganizer and the view updates! Magic!
