Added "Show In FileSystem" right-click option to Scene hierarchy nodes. -Implemented shared function for focusing FileSystem tab and highlighting the node path. -Created right-click option that shows up in the Scene-Hierarchy on Nodes that have a file-system source path. -Created custom icon for this right-click option -Implemented the shared function and icon for other places that already had this features (Open Node tab, Inspector Resource) Co-authored-by: MewPurPur <mew.pur.pur@gmail.com>
