Idea for CodePen plugins (by @tlack)

Step 1: Establish simple plugin architecture/API

```javascript
CP.Plugins.add({
  context: CP.Html,
  re: /fun ([a-z_][a-z0-9_]+)/,
  callback: function(cpPluginContext, match) {
    var str = "function "+match.$1+"() {\n// Comment\n\n}\n";
    cpPluginContext.replace(str);
  }
});
```
Step 2: Allow users to load their own plugin URLs for each pen

Allow users to specify a list of a couple Javascript URLs to load 
for each pen. They'll be created as <script> tags.

Step 3: Allow the community to build the plugin ecosystem

Feature best plugins or at least encourage their creation.

Step 4: Expand API

Allow Intellisense-like plugins, on-save callbacks, etc etc..
