Juan Linietsky 6fc1c3a4d1 Completed the support for plugins! It is not possible to add plugins. 
Not all APIs are provided yet, please request whathever you are missing.
Some example plugins are provided in demos/plugins. Just copy them to a folder in your project named addons/ and then enable them from the project settings.
Have fun!
