Commented Feature: TypeScript Support [291]

Hey there, I tried so hard trying to use TypeScript, but using nodeJS project doesn't seem to support TypeScript VS builders.

I tried modifying the project file:

```
<PropertyGroup Condition="'$(Configuration)' == 'Debug'">
<TypeScriptSourceMap> --module AMD</TypeScriptSourceMap>
</PropertyGroup>
<Target Name="BeforeBuild">
<Message Text="Compiling TypeScript files" />
<Message Text="Executing tsc$(TypeScriptSourceMap) @(TypeScriptCompile ->'"%(fullpath)"', ' ')" />
<Exec Command="tsc$(TypeScriptSourceMap) @(TypeScriptCompile ->'"%(fullpath)"', ' ')" />
</Target>
```

I believe the ProjectExtensions is what conflicting:

```
<ProjectExtensions>
<VisualStudio>
<FlavorProperties GUID="{349c5851-65df-11da-9384-00065b846f21}">
<WebProjectProperties>
<UseIIS>True</UseIIS>
<AutoAssignPort>True</AutoAssignPort>
<DevelopmentServerPort>0</DevelopmentServerPort>
<DevelopmentServerVPath>/</DevelopmentServerVPath>
<IISUrl>http://localhost:2361/</IISUrl>
<NTLMAuthentication>False</NTLMAuthentication>
<UseCustomServer>False</UseCustomServer>
<CustomServerUrl>
</CustomServerUrl>
<SaveServerSettingsInUserFile>False</SaveServerSettingsInUserFile>
</WebProjectProperties>
</FlavorProperties>
</VisualStudio>
</ProjectExtensions>
```

The code I am running is the following:

```
///<reference path='node.d.ts'/>

import http = module('http');

var port = process.env.port || 1337;

http.createServer((req, res) => {
res.writeHead(200, { 'Content-Type': 'text/plain' });
res.end('Hello World\n');
}).listen(port, () => {
console.log("Listening on", port);
});
```

Please make integration with TypeScript possible before release, It becomes a hassle for me to compile stuff outside VS everytime. If I wanted to do that, then I could just use webmatrix or sublime.

Thanks :)
Comments: I had this issue but figure out that I was missing the 'TypeScriptToolsVersion' xmlelement. I'm running 2013 with the public node.js and typescript installs, not the web essentials. Hope that helps...
