Added eslint-disable for @typescript-eslint/no-this-alias in deletetool. This is most likely fixed once the class is upgraded to react anyway.

Reduced CPU-load by limiting the simulation time after node drag events.

Renamed the overlays directory to components.
Typescript now compiles to es6 instead of es5 (es6 content gets translated by babel)

Temporary fix for performance problems in Firefox (dragging nodes still creates memory leaks, but it does not automatically crash now).

Re-enable scope hoisting for parcel build versions.
