This patch does following:
- Removes KJotsConfigDlg (child of KCMultiDialog) and changes the code to just use KConfigDialog
- Changes names of widgets in .ui-file (prepend kcfg_) to let KConfigXT take care of everything.
(this also fixes invalid signal connections to disable label/spinbox when option AutoSave is not checked)
- Changes the layout of .ui-file to QFormLayout instead of QGridLayout with bunch of spacers
- Fixes the inconsistency where KJots kontact plugin had name Notes, but its settings plugin used CfgDlgHierarchy=Notebooks
(because of that, KJotsConfigMisc appeared as a top-level Misc page in Kontact KCM, making in unclear which app do these settings belong)
