ENH: patch to support visual c++ express 2010

Based on value of CMAKE_BUILD_TOOL:

1. customizes the target parameter, either "/target:TARGET" for msbuild (Visual C++ Express 2010) or "/project " for devenv (VS full versions 2008 and 2010)

2. customizes the configuration/platform argument:
msbuild: /p:Configuration=CONFIGURATION /p:Platform=PLATFORM 
devenv: simply "CONFIGURATION|PLATFORM" 

Additionally:

3. adds a check for Slicer_USE_PYTHONQT_WITH_TCL. If true, sets the python_PATCH_COMMAND.  This needs to be conditional because CMake fails if there is no argument for "-P" switch when the patch command is called. The ${script} variable is set under the same conditional Slicer_USE_PYTHONQT_WITH_TCL at line 35.
