title: Read remote properties
body: <p>First of all, Hello everyone(/world) !</p>
  
  <p>I am making an Eclipse RCP app' who needs to inspect some <em>.properties</em> located in some plugins who's Id I know at runtime.</p>
  
  <p>I'd like to know if there is an <em>easy</em> way to read them, for example I know that in my plugin *org.anyname.myplugins.<strong><em>mypluginthatrocks</strong> I have a file named <strong>myawsomeproperties</em></strong>.properties*, how can I open it and read it easyly with a sort of getter/setter system like <pre><code>String getInProperties(String fileNameOrPath,String myPropertieId)
  void setInProperties(String fileNameOrPath,String myPropertieId,String myPropertieValue)</code></pre>or<pre><code>String getInProperties(File file,String myPropertieId)
  void setInProperties(File file,String myPropertieId,String myPropertieValue)</code></pre>or any other mean in that type if you get what I mean ...</p>
  
  <p>Thanks in advance ^^</p>
