[stresstest] Ignore error dumps
Build using Visual Studio's DefaultPlatformToolset

- (BUILD.txt)
New file. Add build notes.

- (*.vcxproj)
Include Global.props property file in all Visual Studio projects.

- (Global.props)
New file. Have PlatformToolset inherit from the DefaultPlatformToolset.

This change is to help maintain compatibility with versions of Visual
Studio > 2010 so that my projects which were created in VS2010 can be
opened and built in any later version using the appropriate toolset (eg
Visual Studio 2012 should compile project using its 2012 compiler) and
without requiring the project to be upgraded.

Refer to the comments in Global.props for more information on this.
