* Show asset path in a (read only) text button. Makes it possible to see the full path in the tooltip, brings support for copying the path and integrates better with the sourrounding layout. Previous label needed lots of space to show the full path without clipping. * Remove "Details" panel, it only contained one item (description). That is moved next to the name and asset path button. * Use property split layout for name source and description buttons. Now that there are multiple buttons, it's better to have a label for them. * Always show operators for asset previews, just gray them out if not applicable instead of hiding. Keeps the layout consistent and graying out is less confusing than hiding UI elements.
