New Material Selection Menu, Compatibility for Minecraft 1.21
• The material selection menu (for rank icons, etc.) has been replaced with a new revamped menu that contains a set of predefered commonly-used materials (wool, terracotta, stained glass, dyes, and other colored items available on your Minecraft version). This is intended to make configuring GrantX more efficient while preventing potentially incompatible/invalid items from being selected. This change also makes opening this menu significantly more performance-friendly. Items that are not listed can still be chosen using the custom search function.
• Added formal support for Minecraft 1.21.
