Feature: Action System (#298)
* Add Action System - Add keyboard test - Add context menu label - Add PanelComponent * Show context menu items based on actions * Add render action feature - Replace bringForward etc buttons with action manager render functions * Move all property changes and canvas into actions * Remove unnecessary functions and add forgotten force update when elements array change * Extract export operations into actions * Add elements and app state as arguments to `keyTest` function * Add key priorities - Sort actions by key priority when handling key presses * Extract copy/paste styles * Add Context Menu Item order - Sort context menu items based on menu item order parameter * Remove unnecessary functions from App component
