Added icon based on the system key when a polycentric user has not set a profile picture. Made managing Polycentric profile most robust. Fixed an issue where latest events were not always being shown in relation to Polycentric profiles. Added copyable (on long press) system key in Polycentric profile activity. Added tutorial videos tab and flow.
