0.8 on 02.10.2008
    - fixed a bug in the string escpape function
      that potentially produced wrong json. shame
      on me
0.7 on 25.9.2008
    - added parse_utf8()
    - added render_utf8()
    - rewrote the render-function inside the cmod
    - the parser is more strict about unicode now,
      hence its not possible to send anything but 
      unicode characters in strings.
0.6 on 22.2.2008
    - uses swscanf for number parsing in case sizeof(p_wchar2) == sizeof(wchar_t)
      instead of copying in to a char* and parsing using sscanf.
0.5 on 2.12.2007
    - fixed a memory leak in the number parsing.
0.4 on 21.05.2007
    - changed the array and mapping parser from using
      the pike stack to collect values (stupid me)

    - fixed some output formating
0.2 on 21.03.2007
