Long Node names truncated issue resolved in WebVOWL

[nandikajain]

Fixes #82
As pointed out in the issue thread, I have implemented the solution where the names are split based on the whitespace and each word is then displayed in separate lines.
The issues arises here in src/webvowl/js/util/:

CenteringTextElement.prototype.addTextline = function ( text, style, prefix, postfix ){
  var truncatedText = textTools.truncate(text, this._textBlock().datum().textWidth(), style);

AbsoluteTextElement.prototype.addTextline = function ( text, style, yShift, prefix, postfix ){
  var truncatedText = textTools.truncate(text, this._textBlock().datum().textWidth(yShift), style);

Here, the text is truncated. If we split the text based on the white spaces and then call addTextLine, the issue gets resolved.

Main changes are done there. Rest all are due to the formatter in VSCode.

@vitalis-wiens The only 2 files that I changed are AbsoluteTextElement.js and CenteringTextElement.js
The package-lock.json got updated on its own, and the rest of the changes are formatting changes which add indentation and line space done by linting in vscode.

While this repo is more or less unactive I checked out the PR and it seems there is still something that need to be done as textoverlow now happens on nodes that are too small
