Multiplayer connection, runtime import, and menu fixes

[parseccentric]

v0.2.2 Release notes

Known Bugs

• The model button color can become dim on multiple presses.
• It may take multiple presses to open the menu after you’ve switched hands.
• The menu position is different between the left- and right-handed versions.
• Invalid models can cause the whole session to halt during loading. (#47)

New Features

• The menu will change from being left-handed to being right-handed, depending on which controller you use to activate it. (Closes #15)

Bug Fixes

• The model list supports a larger number of items. Previously, the font size was variable, causing the texture to be too large, which resulted in missing letters.
• The multiplayer connection happens later in loading so the connection. Previously, it was possible to join a session where you could not see anyone else but they could see you. (Closes #29)
• 3D models that previously had missing textures now load properly. Internally, we replaced Siccity/GLTFUtility with GLTFast. (Closes #45)

Minor Tweaks and Performance Improvements

• Cached models are now detected properly, so they do not get re-downloaded.
• Model button colors are now Komodo Purple.
• The teleport arc is now purple for valid selections and red for invalid selections. (Closes #27)

Domain Module Developer Notes

• Refactorings include name changes, namespace changes, and reducing or removing packages.
  • see commit history for more details.
• Re-added main scene to git.
• In-editor testing with a VR headset now works.
