Even better errors

This release further improves displaying errors in Halunke. Especially errors for sending messages and defining methods.

Better Errors

This release improves the display of errors. This is inspired by Elm. An example:

4 | ("hello" replace (my replac "i" wit "a") with "mumpf")
                     ^^^^^^^^^^^^^^^^^^^^^^^

"str" received the message `replac wit`. It doesn't know how to handle that.
Did you mean `replace with`?

The sarna release (breaking change)

This release (mainly) addresses feedback by @sarna and includes breaking changes:

• Rename to_s to to_string
• Rename to_b to to_boolean
• Rename stdio#p to stdio#examine
• Add a ** method to numbers for exponentiation
• Make (1+2) valid and working syntax.

Some chores:

• Add missing documentation
• Update dependencies
• Clean up (allow tests to run in isolation, rename lexer to tokenizer)
