This removes the file-wise installation rules for Modules and Templates
and instead installs the whole directories.  This approach is much less
error-prone.  The old approach was left from before CMake had the
install(DIRECTORY) command.

Since utility targets have no main output files like executables or
libraries, they do not define an output directory.  This removes a call
to cmTarget::GetDirectory from cmLocalVisualStudio{6,7}Generator for
such targets.

COMP: Don't emit old style cast warning when configured as C++ but still allow being configured as C. Thanks to Monsieur Francois Bertel for the patch.

ENH: Add code to support calling the VS reload macro from Visual Studio 7.1 and 9.0 in addition to 8.0 sp1... Make new macros file with VS 7.1 so that it can be read by 7.1 and later. VS 7.1 does not appear to run the macros while a build is in progress, but does not return any errors either, so for now, the reload macro is not called when using 7.1. If I can figure out how to get 7.1 to execute the macro, I will uncomment the code in cmGlobalVisualStudio71Generator::GetUserMacrosDirectory() to activate executing the macros in VS 7.1, too.

ENH: Add ability to call Visual Studio macros from CMake. Add a CMake Visual Studio macro to reload a solution file automatically if CMake makes changes to .sln files or .vcproj files. Add code to call the macro automatically for any running Visual Studio instances with the .sln file open at the end of the Visual Studio Generate call. Only call the macro if some .sln or .vcproj file changed during Generate. Also, add handling for REG_EXPAND_SZ type to SystemTools::ReadRegistryValue - returned string has environment variable references expanded.

ENH: Removed dependency on Templates/CMakeWindowsSystemConfig.cmake which is no longer used.  Also removed the file itself.

ENH: now target names can be used in add_custom_command() and
add_custom_target() as COMMAND, and cmake will recognize them and replace
them with the actual output path of these executables. Also the dependency
will be added automatically. Test included.
ENH: moved TraceVSDependencies() to the end of GlobalGenerator::Configure(),
so it is done now in one central place

ENH: Added support for import libraries created by executable and module targets.  The module import libraries should never be used but some windows compilers always create them for .dll files since there is no distinction from shared libraries on that platform.  The executable import libraries may be used to create modules that when loaded bind to symbols from the executables.  This is an enhancement related to bug#4210 though not requested by it explicitly.

ENH: Implemented use of cmTarget::GetDirectory() in Visual Studio 6 generator.  This is an incremental fix for bug#4210.

ENH: Adding image version number (major.minor) property to windows binaries.  Default is 0.0, but the VERSION target property may change the value.  Windows now has first-class support for dll and exe versioning.  This addresses bug#1219.

ENH: Several packaging issues. Allow random variables to be passed to cpack (anything starting with CPACK_, add preinstall to the list of dependencies for package, fix typos

BUG: Fixed OUTPUT_NAME feature for VS6 generator.  It was not working for Debug builds and was not paying attention to the executable output path.
