Script files reloaded multiple times #4

When adding N blockly nodes to the Node-Red flow, then the Javascript (and toolbox) files are all loaded N times. See this discussion in the Node-Red forum.

Now the toolboxes are only loaded once per browser page refresh. However at every page refresh all .js and .xml files are still loaded.

Added this in the blokly.js file, to tell the browser that the file needs to be cached during 1 year: res.set('Cache-Control', 'public, max-age=31557600, s-maxage=31557600'); // 1 year

However it doesn't work. After installing ChromeCacheView, it appears that the files are not cached by Chrome ...

The entire script loading mechanism has been changed in the release-1.1.0 branch
