Fix issues related to history (#701)
* Separate UI from Canvas

* Explicitly define history recording

* ActionManager: Set syncActionState during construction instead of in every call

* Add commit to history flag to necessary actions

* Disable undoing during multiElement

* Write custom equality function for UI component to render it only when specific props and elements change

* Remove stale comments about history skipping

* Stop undo/redoing when in resizing element mode

* wip

* correctly reset resizingElement & add undo check

* Separate selection element from the rest of the array and stop redrawing the UI when dragging the selection

* Remove selectionElement from local storage

* Remove unnecessary readonly type casting in actionFinalize

* Fix undo / redo for multi points

* Fix an issue that did not update history when elements were locked

* Disable committing to history for noops

- deleteSelected without deleting anything
- Basic selection

* Use generateEntry only inside history and pass elements and appstate to history

* Update component after every history resume

* Remove last item from the history only if in multi mode

* Resume recording when element type is not selection

* ensure we prevent hotkeys only on writable elements

* Remove selection clearing from history

* Remove one point arrows as they are invisibly small

* Remove shape of elements from local storage

* Fix removing invisible element from the array

* add missing history resuming cases & simplify slice

* fix lint

* don't regenerate elements if no elements deselected

* regenerate elements array on selection

* reset state.selectionElement unconditionally

* Use getter instead of passing appState and scene data through functions to actions

* fix import
