Hey everyone!

Small update here to fix some issues and improve where needed.

Patch notes for 0.1.17a

• Added 'Fill in order' button to the spawner UI for players who have large quantities of custom marbles and want to divide them over spawners.
• Slowed down the rotating force in the MCS editor and it now applies the mouse sensitivity value.
• Renamed template sections to be more clear.
• Custom marble UI now loads in over time to reduce lag spikes.
• Fixed a bug where effects where not saved on existing custom marbles.
