* always set updated topology object when received
* track whether route was set on initial load
* removed connection count from status bar (was not deemed important)
* fixed issue where topology option changes did not affect details pane
* only show filtered nodes when count > 0
* clear nodes graph when empty topology is loaded
* also prevent JS error if nodes are hovered over that should be gone
* fixed options sync issue between graph and status bar
* implemented topology options with immutable DS
- Also added linter configuration, and make linter fail on error
- fixing ES6 errors and added ES6 transformer
- gulp target to try local build
- linted gulpfile
- cant hook into gulp lint yet, because gulp does currently not support
ES6 which some rules demand, since gulp cant transpile itself, we have a
chicken and egg problem.
- ES6 transpiler for test runner
- removed old linter config
- adapted editorconfig to reflect linter config
