* Fix handlabeler/utility belt misprediction

* Partly moved HandLabelerSystem to shared
And cleaned up HandLabelerComponent

* WIP format the files so later commits look clearer
Doesn't change individual code lines, but may move
functions to another file

* WIP some more code movement

* Hand Labeler is now mostly predicted
Only the UI isn't

* WIP: Formatting and moved stuff

* Using componentstates for prediction correction

* review

* Update label on label change
