Alpha v0.10.1

Iterator QOL improvements & more.

This update brings a much needed quality of life feature that's been missing from chaiNNer for quite a while now: the ability to drag nodes that are already placed down into iterators. I have seen lots of confusion among people new to chaiNNer that did not realize you needed to drag and drop from the selection panel into the iterator in order to use it properly. Now, that is no longer a concern.

Now, you can drag any node into the iterator area and it will automatically be placed inside the iterator. You can even select and drag multiple nodes in at once, meaning you can now convert an existing chain into an iterable chain fairly easily. To get a node out of an iterator, a new option has been added to the right-click context menu to "release" the node from the iterator. It will then be placed outside the iterator for you to use there.

I really hope this makes using iterators a lot less painful.
