	Changes nuget references to ProjectReferences in FeatureSamples.
	Nuget doesn't support ItemGroups with conditions (it will overwrite them on the next package update) so that's why this script exists
	By default, this utility removes urho.targets imports with native libs, use "-refsonly" arg to replace only <Reference>s
