GhostTrails 3.8.0.0 - 3ds Max 2017-2025 plugins

GhostTrails builds for 3ds Max 2017 up to 3ds Max 2025
Thanks fly to the original plugin creator @andrewkreid to make the source available on github

• no code change besides some minor 3ds Max 2025 SDK compatiblity fixes
• heavily modified visual studio project structure using property sheets,
• 3ds Max SDK created environment variables and internal MAX_RELEASE_xx #define macros instead of custom ones

As result, future 3ds Max SDK releases should only require minimal adaptions ( essentially adding new build targets is enough )
