Currently, it's hard to figure out the idname of a node when just looking at it
in the node editor. while most users don't need this information, it's very
useful for Python developers.
This patch adds the node idname to the tooltip that shows up when hovering over
the node header. It only shows if "Python Tooltips" is enabled in the
preferences.
This also fixes a bug where the dynamic node description wouldn't show when the
node is collapsed.
