Unified the approach to gathering assets and spawning nodes from them. Previously each had its own slightly unique code doing similar things. Note that with this change it is now possible to directly spawn 'evaluator' style nodes from the context menu instead of relying on a context menu conversion step. Also tweaked icons, tooltips and titles for consistency #rb Jurre.deBaare [CL 16434364 by Thomas Sarkanen in ue5-main branch]
