Add support to find all versions of visual studio

[clmcgrath]

Can this be modified to find previous versions of visual studio
while the functionality is useful for finding 2017 we have a lot of legacy projects with dependencies as early as 2010

.\vswhere.exe -version "[11.0,16.0)"

only returns 2017 skus

vswhere already supports finding the installation path for Visual Studio 2010 and has for a while. If you're not seeing that behavior, please update to a newer version of vswhere. You also need to pass -legacy as documented in the -h usage information. But -version will not work without Visual Studio 2017 installed. See issue #91 for details.
