EditBar improvement

[labronico0586]

It is meaningful to use CopyPaste interaction with the Transform control (and interaction) as explained in http://viglino.github.io/ol-ext/examples/bar/map.control.editbar.html example.

So it could be useful to add Cut, Copy and Paste buttons to a Bar (subbar) activated when the Transform control is activated (as it happens in Select control in the EditBar).

The request is to add a way to do that.

The proposal is:

1. add name (optional using options parameter) for all controls used in EditBar, so it could possible to get them later using getControlByName function;
2. add setSubBar function to Toggle control, in order to add (or remove) a bar in control (now it is possible only in constructor)

💡 Great idea... this was missing! 👍
Added in the last commit 🚀

var mySubBar = new ol.control.Bar()
// Add a sub-bar to the Transform button
editBar.getControlsByName('Transform')[0].setSubBar(mySubBar);

The name is the one of the interaction:

var ctrl = editBar.getControlsByName('Transform')[0];
var inter = edit.getInteraction('Transform');
// For draw interaction : DrawPoint, DrawLine, DrawPolygon, DrawRegular
var ctrl = editBar.getControlsByName('DrawPolygon')[0];
var inter = edit.getInteraction('DrawPolygon');

That's a great notice! Thanks.
But why you called the new method to add a bar SetSubBar instead of setSubBar. It breaks your naming rules...

It's a typo 😞
