Customized and draggable favorites view(#626)

[kristavlastou]

So me and @EvaNtziou implemented the features described in issue #626 for the favorites section.
So now you can:
1.Add or remove an item from favorites
2.Add more than one item to favorites at the same time if multiple items are selected
3.Be able to drag files and folders from the desktop to the favorites view

We did our best but we work on Windows so let us know if any issue occurs when you merge it. We are more than happy to help resolve it to ensure the best result!
Thank you very much
Below is a reference picture of how it looks like :

Hi @kristavlastou,
Thank you very much for this PR. I will test and get back to you soon.

Manually tested, found a blocking issue. I am unable to open a folder window in my local instance of Puter after this change. The following console error is logged.

(as an aside, the verbose print of "Sidebar droppable initialized" should also be removed)

For additional information, I checked the line in UIWindow it's complaining about and I see that it's an iterator on window.sidebar_items (second line here):

                let items = JSON.parse(window.sidebar_items);
                for(let item of items){

In the development console, window.sidebar_items evaluates to null.

Okay thank you for your feedback ! We checked and changed some parts of the code and it has to be working now. If something occurs let us know!

Hi @kristavlastou, I was testing this and I can't really open the explorer any longer. When I click it, I get the following error:
