Replaces #534

This is a general thread for suggestions related to additional cosmetic variants for Railcraft's Cosmetic Blocks. Some general proposals so far that I thought of:

Ornate --Rename--> Chiseled (Consistency with Vanilla Minecraft, allows for some actually ornate blocks in the future)
Add Ornate Variant (Creates a pattern similar to Vanilla Chiseled Quartz)
Etched --Rename--> Creeper Etched
Add Blaze Etched (Requires Blaze Powder, etches a Blaze Face on the block)
Add Tiled (Creates a pattern similar to Vanilla Purpur Blocks)
Add Pillar (Creates a pattern similar to Vanilla Quartz Pillars)
Add Ornate Pillar (Creates a pattern similar to Vanilla Purpur Pillars)
Add Cracked (Create a cracking pattern, similar to Vanilla Cracked Stone Bricks)

Other suggestions are welcome and encouraged.

The Etched and Ornate stones are all just recolors! So boring! The blocks mostly suggest their theme, perhaps someone can make cool textures?

Etched Blood Stained: Vampire Face
Ornate Blood Stained: Bloody swirls?
Etched Nether: Blaze Face
Ornate Nether: Nether Portal?
Etched Abyssal: Tentacles
Ornate Abyssal: Giant squid eye?
Ornate Infernal: Wither skeleton skull
Etched Infernal: ???
Etched Sandy: Keep the creeper
Ornate Sandy: Keep the chiseling
Etched Bleached Bone: Skeleton skull
Ornate Bleached Bone: Vertebra?
Etched Quarried: ???
Ornate Quarried: ???
Etched Frostbound: Cracked ice?
Ornate Frostbound: Snowflake?
