ENH: Renamed cmStringStream to cmOStringStream and added cmIStringStream.  Removed cmInputStringStream.

Add configure option and fix potential bug in other targets. Now the run command is actually run with directory, so eventually we should be able to run this from a subdirectory

Fix for run command on windows. If you specify command in quotes but not full path, it should still work

Add some minimal Dart capability to ctest. For example now you can actually use ctest to build projects, do cvs update on all platforms. This is especially cool for Visual Studio where you do not want to load the whole development environment just to build your project.

ENH: nmake now uses incremental linking as Msdev does. Faster build (linking a static vtk.exe or paraview.exe could take more than 10 minutes)

If you specify header file as source, it should still use C compiler and not CXX. Also fix COnly test so that it make sure that this still works...
