Added initial MinecraftEdu

Need to 1) unpack jar 2) create pkg based off of jar 3) create app for
launcher
Now fully works
Finished testing MinecraftEdu recipe

Now supports running Munki recipe.  You *NEED* to download the
minecraftedu installer jar file and then rename it “minecraft.jar” and
place it into the Cache folder for this recipe.  Run the recipe once to
create the folder, and then place the .jar file inside.
Merge branch 'development'
