Lighting, Editable Heads, Popular Online Category, and Basketball Updates

I didn't post an announcement for the previous three big updates, so I've rolled all 4 update notes into one here!

New major features:

• Apply mesh simplification on meshes outside of arm's reach. This enables (up to) 2x visible detail in large worlds!

• Can now browse the online gallery by "Newest" or "Popular"!

• Can now view your own online saves in the gallery to know what you have in each of your 5 online slots!

• Player heads are now editable in multiplayer! Sculpt on eachother's heads in real time or shoot eachother with rockets!

• You now have 5 head save slots to keep all your favorite avatars ready to go!

• New Prompt Generator Tool pops up a random sculpture suggestion for when you get stumped or want to play "Sculptionary"!

• Menu refactor: There's no longer a back-of-the-hand menu. It's all done with tabs on the front of the hand!

• Added a basketball! This is a networked ball that can be tossed around between players in multiplayer, or shot with rockets!

• Now you can place a point light into your sculpture to add lighting to your creation!

• You can now change the color of the sun/sky by selecting a color while holing the SkyGrab Pointer!

Other Improvements:

• Stamp menu is now less confusing (hopefully).

• Players joining a multiplayer game now don't get sculpting tools until after receiving the sculpture.

• Undo leaving player's actions popup now has a different look than the save reminder popup to prevent accidental habitual 'yes' clicks.

• Automatically check for multiplayer games on startup to increase the chances of finding games.

• Dotted box appears around head sculptures when your tool is nearby to show that head is editable.

• Added a "repair head" button in the avatar menu so you can regenerate your head after getting shot by rockets.

• The "no internet" popup shouldn't appear during brief internet hiccups anymore

• Explore mode is no longer a seperate mode. Explore tools are simply selectable in your tools list.

• Multiplayer Host/Join are joined into one menu.

• If you want to disable grip movement, that is in the settings now.

• Rockets now fire attached to the sculpture so that all players see the rockets hit the same location even when moving sculptures around.

• Add the Liv plugin for mixed reality.

• Can now permanently dismiss the save reminder popup.

• You can now zoom in and out with the camera tool.

• Camera now shows you a display in selfie mode so you can line up photos.

• Speed up loading from disk by 20%, and use less memory doing so.

• Reduced compute expense of carving particles by 20%.

• Prevent the user from accidentally changing tools while in the middle of a brush stroke.

• When you open the reference images panel the first time, it now places a text file in the SculptrVR reference image folder to help people find the correct location.

• Export finding instruction now show up on a panel that sticks around until dismissed. Instructions have been made more more clear.

• Multiplayer panel improved and now shows a picture of your avatar when openned.

Bug Fixes:

• Hovering over the current tool now always opens up the horizontal menu

• Fixed a bug that would erroneously report "internet connection lost"

• Fixed bug where voxel cube brush would delete a little bit beyond its bounds

• Save reminders now work for everyone in multiplayer, not just the host

• Layer panel now works correctly in multiplayer for clients

• Fix Various head-related network bugs

• The floor now stays at the appropriate ground level when loading a new procedural scene

• Fix particles sometimes getting their rotation
