Fixed node filtering and design. Nodes may still change color during filter operations. This should be resolved when colors are hard-mapped to node types.

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)
