Add a feature that allows scripts to be pinned or locked

[living2room]

I recommend adding a feature to the script editor that allows scripts to be pinned or locked.

The pinned scripts would always stay at the top position.

With the locking feature, the script would not switch automatically when other nodes are clicked, unless the script is attached to the node being clicked, in which case it would still switch and unlock automatically. Also, locked scripts would not be closed when selecting ‘Close All’ from the right-click context menu

I would really like to have this feature. I have a _todo.txt and some other scripts like utils.gd and global.gd, which I always use. But the list is polluted by script I don't need every time and currently I use "Close all but this", but then I have to open my needed files always again.
