Clean up code and improve documentation

This switches the code documentation genarator (we're now using phpdoc
instead of NaturalDoc).

Also various small code cleanup tasks:

- Remove unused code
- Get rid of `and` / `or`, we're using `&&` / `||` now
- Adding missing return values
- Helping PhpStorm to detect some dynamically called functions
  (mark_builtin_callable in Transcompiler)
- Reword transcompiling => compiling in documentation
