title: Trac plugin with support for HTTP get parameters
body: <p>I am fairly new to Trac plugins and python in general. For most of this day I have been looking for a way to get parameters into a Trac plugin that I am creating, via URL request.</p>
  
  <p>So if I had a plugin on site <em>wikitest</em>, I could access it like this, and also provide an argument:</p>
  
  <pre><code>http://localhost:8080/tracEnvironment/wiki/wikiTest?name=annie
  </code></pre>
  
  <p>Then my plugin, located on <em>wikitest</em> could get the name provided via URL.
  Is this possible? </p>
  
  <p>I have found some answers to similar problems, that suggest using a python framework, but I think that my case is different, because I'm dealing with Trac plugin, instead of standalone script. </p>
  
  <p>What would be the best way to get this data to my plugin?</p>
