• Added all permutations of the "Window1x1Slope" block
  
• Adjusted the recipes of the "Window1x1Flat" block, which somehow got changed back to the default recipe for every block, even though I know I changed these recipes before.
  
• Removed all modded blocks from the "Window Blocks" category, and instead added new separate categories for each type of block. (1x1Flat, 1x1Side, etc.), to eliminate clutter.

• Adjusted recipes for the "Window 1x1 Side" blocks.

• Fixed all the small block recipes, which were still the same as all the large block equivalents.
  
• Learned how to setup proper block mirroring and set this up for all previous blocks.
  
• Remodeled and added permutations for the "Window 1x1 Side" block
  
• Added "Inv." versions of all the "Window 1x1 Side" blocks, since for some reason this didn't already exist.
  
• Re-worked models for all the standalone corners in the "Window 1x1 Flat" blocks to allow the blocks and edges to line up nice and neat with all the edges for all the other blocks, including the new "Window 1x1 Side" blocks.

• Reworked Blender models to use a single .blend file and linked geometry.
  
• Added small versions for Window1x1Flat
