began working on compacting the API for simplified extension writing
- code does not compile yet, must solve some design issues first
removed st_op_copy, foreach transformation in progress
core can be compiled now, moving on to stdlib
compacted the array object
converted closure and dict, only class left
fixed up stdlib core, now only stdlib ext left to fix
everything compiles, `foreach` doesn't work
fixed foreach issue, found another bug in json code
fixed the foreach API and finally fixed foreach itself. memleak left.
added iterator->data reference for array, disabled bad string table
fixed most issues
