ENH: Added kwsys::String class to shorten debugging symbols and error messages involving std::string.

BUG: When more than one command is given and one of them fails to start and the rest are killed, do not forget to reap the killed children.

ENH: Improved robustness of sharing parent pipes with children.  This ensures that the parent pipe handles are inherited by the children.  If a parent pipe handle is invalid a handle to an empty pipe is given to the child to make sure all pipes are defined for the children.

BUG: Do not close handle obtained from GetModuleHandle which does not increase the reference count of the module.

ENH: Change flag to PASS_REGULAR_EXPRESSION and FAIL_REGULAR_EXPRESSION and add help in cmSetTestsPropertiesCommand

ENH: Improved file modification time comparison on Windows to use GetFileAttributesEx instead of CreateFile/GetFileTime/CloseHandle to get file times.  This results in a 30% reduction in time to do a build system check.

ENH: avoid the use of GET_TARGET_PROPERTY by testing the CMake executable instead of the test executable

BUG: Reverting fundamental type info change until it is fixed on more platforms.  It was tested on Linux, SGI, HP, Sun, OSX, Windows with nmake and VS 6, 7, 7.1, 8, Borland Make, and cygwin by hand with spaces in the path and cmake 2.0 and 2.2 before committing but still seems to be failing on some dashboards...strange.

ENH: Converting FundamentalType try-compiles into a single try-run.  All the information about the existence, size, and signedness of types can be determined in one program thanks to limits.h.
