Release v1.1

* Made tests interpretable by OCaml again.
* Added a formatter and reformatted all tests.
* Added a nice, AI generated image of a camel.
* Cleaned up shell scripts.
* Extended the grammar just a bit. Now we use optimistic parsing.
Valid programs should be parsable, but invalid programs can too. :D
* Fixed usage of brackets and added syntactic sugar for lists.
* Refactored the interpreter. Especially, I have changed the
memory management.
