labcomm_encoder_ioctl_)

  corrected encodeBoolean
  changed encodePacked32
  added a flush to end() method

lib/csharp/se/lth/control/labcomm/LabCommDecoderChannel.cs:
  corrected struct handling
  corrected readInt
  changed decodePacked32  

  put delimiter first in typeinfo to simplify parsing
  and not assume what delimiter should be used for
  various languages (was broken for C#)

compiler/CS_CodeGen.jrag:
  corrected handling of variable sized arrays (int -> packed32)

compiler/Python_CodeGen.jrag:
  added signature list 

C typeinfo now includes the cprefix. 

continuation bit. C# is currently (intentionally) broken. 
Java and Python are untested.

labcomm_encode_type_index, labcomm_encoder_end

Added test of generated C encoders.

encoder indices (linker magic provided). 

Testcase for some of the encoding/decoding functions.
