* Add PatchManager - Allows you to patch terrain.png and items.png on the fly.

This can be used for modding, since you don't need to share copyrighted Mojang assets alongside your texture patches.

+#Texture patch data for Minecraft PE.  The # at the start denotes a comment, removing it makes it a command.
+# Commands you can use:
+# - terrain|x|y|filename   -- Patches terrain.png
+# - items|x|y|filename     -- Patches gui/items.png
+# - vegetation_tint|bool   -- Enables default vegetation tint. (grass and leaves)
+# - metal_block_sides|int  -- Makes metal blocks have separate side textures, and allows specification of their Y offset. -1 to disable.
+
+# * The filename parameter will be a PNG file that can be found relative to this directory. For example, '../quiver.png' will load it from assets/, 'chain.png' will load it from assets/patches/.
+# * The X and Y destination coordinates will be multiplied by 16.
+# * The texture doesn't have to be 16x16, all of it will be patched on to terrain.png.
+
+
+# Below is an example of what you can do:
