Add a list component to add items without transfering the whole data.

[T4rk1n]

If you have a list of items to render and you just want to add an item on the fly you currently require to have the list of initial components and append the new element to the list and send it back.

Operations on items:

• append: Add an item to the end of the list.
• prepend: Add an item to the start of the list.
• concat: Concatenate another list with the current items.
• insert: Insert an item at an index position.
• delete: Delete an item at the index.

Also have a max_size aspect, when adding items it pops extra items either from the back or front depending on the insertion position.
