- added a wire-type ITEM_REAL (for DoubleElements) (we could technically
  use ITEM_INT with the current code, but certainly not ITEM_UTF8).
  if we keep this one, we need to add it to the other versions too (python&ruby)
- Bad boolean values in the string format returned a Null ElementPtr instead of   raising an exception.
- Fixed decoding of True values off the wire
- Removed a few checks that aren't needed
- Fixed a null-termination problem when encoding big packets (i.e. > 256 and
  > 65535 bytes)
