Hide some DrawSvg menu items

[bartbutenaers]

Some of the DrawSvg menu items are not relevant in our context, so they should be removed:

Not sure whether we have to remove Google maps: Users already have the worldmap node, and moreover this option won't be available anyway in the offline version.

Not sure whether we have to remove the media? During development of my node-red-contrib-ui-camera-viewer node I had lots of issue with the foreignobject (which is being used to embed these media elements inside an SVG) on some browsers ...

Steve (@Steve-Mcl),

• Do you agree to remove these items?
• I'm not sure how you managed to remove the "Save" menu item? Did you only add following statement to accomplish this:

  window.drawSvgCommChannel.call({
   method: "setDocumentMenu",
      params: {
         // enable samples sub-menu
         'enableSamples' : true,
         // disable save (handled manually)
         'disableTasks' : 'save'
  },

  Because when I change this to 'disableTasks' : 'save new open', only the 'save' button is invisible, but the other two buttons are only disabled...

Bart, I am thinking, as the author is (rightly) keen to control his product, perhaps we might offer some concessions to ease his worries. i.e. Ask the author to have a build that actually removes the "new", "load", "save" functionality completely - meaning anyone copying our local version will have a reduced functioning version.

As for media elements, I am not certain we should remove these - might be beneficial. At minimum, if we had the API to remove/hide the buttons?

As for maps - its a nice to have anyway (I believe it generates an image - not embed a map - so if a user wanted an image of a map, they could do this themselves).
