ERR: Small bug in generated DSP file fixed.  A custom command environment variable has been replaced with explicity writing out the command.

ENH: Added SOURCE_GROUP command and corresponding support code.  This command allows CMakeLists files to specify how sources are organized into groups in the generated DSP files and makefiles.

ENH: Added text files group to DSP output.  CMakeLists.txt is duplicated in this group and outside, but fixing this will require a reorganization of custom rule generation.  I should get to that soon.

ENH: Finished Simplifying dsptemplate processing with  in place of separate Release, Debug, ReleaseDLL, ... configurations.

ERR: Fixed library path problem for ReleaseMinSize build.   should now be used in place of separate Release, Debug, and ReleaseMinSize.

ENH: added a config setup file for CMakeSetup.   Cleaned up the names of the source and binary directories

ENH: CMake and configure now use SUBDIRS in CMakeLists.txt to find all the directories of the system.
