Added scoping.

ste:mktag generated tags now have an own scope. They even resemble
closures, since they inherit their parent scope.

A lot of work was done to keep this compatible with older programs.
However:

* Templates that relied on the non-scoping behavior of tags will probably
  fail.
* Since $ste->vars is no longer an actual array, things like
    $ste->vars["foo"]["bar"] = "baz"
  are no longer possible! A single field access will still work:
    $ste->vars["foo"] = "bar"
