TalkDetailsWidget is consctructed with current date/time
Switced connection to clicked signal instead of activated signal for qtableview.
This enables support for Ubuntu clicking, but removes keyboard activation by pressing enter.
Enabled calendar selection picker for dateEdit
Switched date and time labels/edits to single datetime field to work with QDataWidgetMapper
Added import CSS and RSS fields to widget (not functional)
Import CVS and RSS now function correctly
