title: Prevent optimization of text! and json! plugins on requirejs optimization tool
body: <p>I'm using the following architecture for my multipage requirejs based application.:
  <a href="https://github.com/requirejs/example-multipage-shim" rel="nofollow">https://github.com/requirejs/example-multipage-shim</a></p>
  
  <p>The repository explains how to optimize the application by running r.js, the command line tool used for this kind of task.</p>
  
  <p>Everything should work fine but my project as some modules that have dependencies that perform HTTP GET request to fetch data from server (wich can be text or json)</p>
  
  <p>This is because some of my jsons and templates used by some pages need to be server-side processed for localization. </p>
  
  <p><strong>Here is a basic example to show what i'm talking about:</strong></p>
  
  <pre><code> define( function( require ){
  
      var appLang = require('json!/pagelang/login'),           //(a)
          loginTemplate = require('text!/template/login'),     //(b)
          module = require('app/model/user'),                  //(c)
          ....
  </code></pre>
  
  <p>An HTTP get request is made to my server localhost/pagelang/login
  which returns a json</p>
  
  <pre><code>{
     "hash": "translated_value",
      ...
  }     
  </code></pre>
  
  <p>The same applied for <code>template/template_name</code>where an html with it's UI translated into the user language is returned from the server.</p>
  
  <p>By running r.js it attempts to load those locations for an existant directory directory on the server, which obviously, don't exist. </p>
  
  <pre><code>Tracing dependencies for: app/main/login
  Error: Error: Loader plugin did not call the load callback in the build:
  json:
    json!/pagelang/login: Error: ENOENT, no such file or directory '/pagelang/login'
  Module loading did not complete for: app/main/login
  </code></pre>
  
  <p><strong>So, i would like to prevent the command line tool from optimizing text! and json! modules. Is it possible?</strong></p>
  
  <p>I checked requirejs build settings but i didn't find the solution for my problem. Any help?
