Blender 5.x support and a round of crash fixes.

Upgrading on Blender 4.2 or later: first remove the old "Ultimate Rock Generator v2" add-on (Preferences > Add-ons > Remove), then install this ZIP. It now installs as an Extension, and two copies enabled at once will conflict.

• Blender 4.0 to 5.2, tested on 4.5 and 5.2 LTS. Installs as an Extension on 4.2 and later (Get Extensions > Install from Disk).
• Fixed: Musgrave layers crashing on Blender 4.1 and later (the node was removed from Blender; the layer now uses the equivalent Noise Texture setup).
• Fixed: Distorted Noise controls raising errors, including a broken contrast control.
• Fixed: Decimate Ratio and Target Faces erroring when edited.
• Fixed: rare error when generating smart seams, manual seams or unwrapping.
• Fixed: adding the Sun light from the material popup no longer deselects your rock.
• Fixed: the Stylized material now uses your current slider values when assigned.
• Fixed: selecting sculpt brushes on Blender 4.3 and later.
• Custom material presets are now stored in Blender's extension user folder, so they survive updates.
• New: Support (Discord) button in the main panel, linking to the 3D Texel Discord.
