refactoring away for loop macros
* remove experimental for loop macro usage
* make implementation of several operations follow data structure
(recursive data -> recursive implementation)
* rename getSize -> bitsof to avoid bits vs bytes confusion
* fix potential 32-bit issue where asSignedWords cast to `int` even when
`uint64` was used as storage
* `hi` for signed ints now is signed - this replaces `asSignedWords` and
makes several int operations more natural
* fix bit size assert

zah 6ae8de932d Add explicit generic conversion operators (#56)
The new `to` operators that can be used to constuct Stint types from
regular integer types. These are intented for usage in generic code
such as rlp.nim

Also fixes a bug preventing construction of Stint values from unsigned
integers (because they lack an unary `-` operator).
