Create a recipe for Haiku2048
A 2048 clone was written during Google Code-In 2015 but no recipe was made for it.
The sources are here: https://github.com/TwoFX/Haiku2048
The recipe should be added to haikuports at haikuports/haiku-games/haiku2048/.
Important: please read the generic instructions for "recipe" tasks, as we have a lot of these: https://dev.haiku-os.org/wiki/GoogleCodeInTaskRecipe
