FIxing path separator to address #247

[aaronpowell]

When investigating #247 I noticed that the NODE_PATH would look something like:

C:\tmp\.nvm\v6.3.1\node_modules:C:\_code\project\node_modules

The problem is that the path separator is : not ;.

This fix have resolve the issue in my testing.

Testing fix

1. Create a new project using the yeoman generator
2. Enable server side rendering
3. Set NODE_PATH to have a value (eg: C:\tmp)
4. Run the application and experience the error described in Can't find aspnet-prerendering when using a node version manager #247
5. Apply patch
6. Run the application successfully

Hmm just noticed that : is what *nix seems to use as a path separator (testing using Bash on Ubuntu on Windows). My primary dev environment is Windows.

Fixing to use Path.PathSeparator like it should do to pick ; or :.

@aaronpowell I've pushed an updated set of beta packages (NodeServices, SpaServices, etc., all versioned 1.0.0-beta-000010), so your fix should be present in any new projects you create, or in existing ones if you force it to update the NuGet packages. Thanks again for the PR!
