Implement beginnings of joint session history

Fix backward navigation

make use of history iterator

Add frame iterator
add different back logic

cleanup navigation_info

Add extra explanation for iter logic

Remove forward history on full frame tree

Rename navigation to traversal where appropriate

check full tree for can go back/forward

simplify frame iter logic

remove FrameIterator

cleanup history iter

reduce amount of vec allocations

removed extra parenthesis

Remove history iterator

cleanup after rebasing

avoid recursive vec allocation
remove full_frame_tree
remove_forward_history_in_frame_tree -> clear_joint_session_future
