Support native libraries

[GlitchEnzo]

Unity is terrible with it's handling of native DLLs, so this tool must provide some sort of additional support for them.

Unity requires native DLLs to be in the Assets/Plugins directory BUT Unity locks the files and there is no way to get it to release the lock without closing the Editor. This creates complications such as saving any open scene, closing, copying/overwriting whatever DLLs need to be copied, re-opening Unity with whatever scene/project it had open, and continuing with the installation of the packages.

Since it is the Unity Editor itself that locks the files, it's doubtful that there is any change that can be done to NuGetForUnity to resolve this.

I don't believe the Unity plugin folder is a requirement anymore.

Plugin Inspector: new native plugin importing system. You're no longer required to place platform specific plugins into special folders like Assets/Plugins/iOS, Assets/Plugins/X64, etc. From now on, you can place them anywhere.
You can set platform compatibility settings by clicking on the plugin (files with extensions *.dll, *.so, etc, and folders with extension *.bundle), this include both managed and native files. Plugins can be set for “Any” platform, “Editor only” or a specific platform.
Platform specific settings can also be set, e.g. CPU type. Different platforms may have different settings.
