Bug Fixes in KDE-PIM
Disable the Special Dates and Planner plugins by default.
A new option is introduced for kdepim 4.4.10: KONTACT_ENABLE_MIXEDMODE_SUMMARY_PLUGINS (default: disabled)
This will prevent Kontact from starting twice when restoring the KDE session.
(and probably a few other Kontact bugs)
DO NOT BACKPORT. AFAIK, kontact from 4.6 is not affected.
