devel/lfcbase,databases/cego: update 1.18.3 -> 1.18.5, 2.48.19 -> 2.48.23

lfcbase:

• Added scrollable feature to Screen2::Message, so longer messages can now be handled by the panel
• improvements for Screen2:Message panel

cego:

• Added default append mode setting for tableset. WIth cgadm the appendmode can be setup ( e.g. enable appendmode for TS1 ) It may be useful to have enabled appendmode at default for insert intensive tableset configurations
• Fix added for CegoAdmScreen in tableset parameter panel. Initfile was not setup correctly ( null value indicated, should be empty string )
• Changes in CegoAdmScreen::DBThread panel to show long queries with new Screen2::Message panel
• Patch added in CegoTableManager::updateTuple, reactivated evalExtTableReferences method call, since this is needed for update with nested selects, where external attributes are referenced in combination with enabled query cache ( e.g. update t1 set a = ( select a from t2 where t1.b = t2.b ) )
