[Bug] Components Use Wrong Slash in .csproj

[Tessalator]

When creating a Component in the Asset Browser (Create -> Create C# Component) an incorrect entry gets made in the VS Project File.

Here, the `SlashTest` entry is created when a `SlashTest` component is created. It uses a forward slash. The convention is a backslash. Other Unigine entries are correct.

	<ItemGroup>
		<Compile Include="data\HotSwap.cs"/>
		<Compile Include="data/SlashTest.cs"/>
	</ItemGroup>
	<ItemGroup>
		<Compile Include="source\AppEditorLogic.cs"/>
		<Compile Include="source\AppSystemLogic.cs"/>
		<Compile Include="source\AppWorldLogic.cs"/>
		<Compile Include="source\main.cs"/>
	</ItemGroup>

`Hot swap` is just a file created in the IDE for reference.

Visual Studio doesn't care, but this becomes a problem with things like refactoring. Tooling does not always recognize the forward slash and will add an entry with the back slash. This can lead to a confusing situation where the IDE reports a duplicate declaration error (red lined), but the project still compiles.
