Implement plugin object support; pass dot to app 

We now support plugins that are more than functions. At the moment these
plugin modules should export a plain object with the following possible
properties:

  * priority number
    * preload/load priority. Higher numbers result in earlier calling.
  * preload function
    * Any logic for preloading, just as dynamic/initial setup that may be used by other plugins.
  * load
    * Any logic for setting up the bulk of the plugin, such as express paths and similar.
