Nicolas Boulenguez fbfe6784d2 Change quasiquote algorithm
- Add a `vec` built-in function in step7 so that `quasiquote` does not
  require `apply` from step9.
- Introduce quasiquoteexpand special in order to help debugging step7.
  This may also prepare newcomers to understand step8.
- Add soft tests.
- Do not quote numbers, strings and so on.

Should ideally have been in separate commits:
- elisp: simplify and fix (keyword :k)
- factor: fix copy/paste error in let*/step7, simplify eval-ast.
- guile: improve list/vector types
- haskell: revert evaluation during quasiquote
- logo, make: cosmetic issues

Wren implementation

Adding a time function

Since Wren doesn't have a time function, we add a System.gettimeofday function which returns a float with the number of seconds since epoch (with fractions of seconds).

This is done by applying the patch in wren-add-gettimeofday.path to Wren's source code before compiling it (see Dockerfile).

Wren interop

See examples in tests/stepA_mal.mal for usage of wren-eval to evaluate Wren expressions inside a Mal program.
