Texture Backport for Beta

This texture pack backports the modern textures to Beta 1.7.3. Support for more versions may be added in the future.  The water and lava textures are still procedurally animated using the old algorithm, so they don't really look like they do in modern versions. More screenshots are available in the [gallery](https://modrinth.com/resourcepack/texture-backport-for-beta/gallery).
