add "sub" bool to Attach return, not used yet
simplify uc code
fix bug where sub/super tasks arent removed when switching tasks
replace regular bool with state to differentiate between just returning and between returning with sub = true
rename subController from before to internalController to avoid confusion
return right state for pri and taskpicker
rework for loop and stack to work with states rather than specialcasing priority and taskpicker
reword badly worded comment
support adding new task through taskpicker
instead of having an explicit sub, always keep history and have an explicit "back" action, neither is perfect, but this sees a bit smoother
parent is no longer used
plans for the future
