Change texture pack description file name
Change the name for texture pack description files from "info.txt" to "description.txt" in order to keep the naming consistent between description files for both mods and texture packs. Also add backwards compatibility for texture packs that use "info.txt", and note in the log that "info.txt" is depreciated.
