Add ability to remove from queue

[n-ce]

Currently there is no way to remove unwanted streams from queue. We would like to work on a removal system.

Implementation

• Have a delete button beside shuffle button.
• Onclick delete button will toggle delete mode.
• In delete mode, each queue item will have a remove button to their lefts.
• onclick remove button will remove clicked item from QueueArray (memory) & QueueList (UI)
