Added required include file on Linux.
Initial commit of new source files for Omega Temperature controller.  They still have the same code from the Biosciences Tools files they were copied from, but they compile and link.
Adding CMake files to build libmodbus under Visual Studio.  There are a required stdint.h and config.h files that have to be copied into the libmodbus/src directory along with the CMakeLists.txt file to make it compile.  If you are not using Visual Studio, then compile and install using the automake setup in libmodbus directly.
Adding CMake find for Modbus library.  Also added configuration for VRPN_USE_MODBUS that will include the library if it is used in Visual Studio, and will add include and libs in Cmake. Also fixed vrpn_USE_MPI to VRPN_USE_MPI so that it will work when it is finally implemented.
Initializing timestamp before using.
Declaring unsigned value to match use in code.
Fixed mis-spelling in definition to avoid errors on Visual Studio.
Only includes the source and device for vrpn_OmegaTemperature device when Modbus is found and configured.
Enabling VRPN to compile using Winsock2 using either a vrpn_Configure.h or Cmake setting.  Making the OmegaTemperature only compile when Modbus and Winsock2 (which is required for Modbus) are both turned on.
Starting to add things needed to convert this program to use modbus rather than serial port to communicate.
Fixing the configuration file for Libmodbus under Visual Studio so that it defines a required function.  This lets us call a Modbus function and still be able to link.
Added comments describing how to build Libmodbus under Visual Studio 2008.
Adding comments where changes are needed to get to a version that can be pulled into the master branch to bring in the bug fixes and winsock2 feature.
Merge remote-tracking branch 'upstream/master'
Fixed some bad merges from upstream/master.
