This patch revises the implementation of nitpicker in the following respects: - Split the implementation into smaller files, - Consistently use the 'Nitpicker' namespace, - Avoid the use of format strings, - Retire old (and hackish) debug mode, - Removal of unused timer connection, - Merging 'Session' into 'Session_component', - Merging 'Mode' into 'User_state', - Adding the notions of 'View_owner' and 'Focus' as interfaces, - Untangle 'User_state' and 'View_stack'
