move the dispatcher service inside the editor addon

it seems farfetched that the current code will evolve into an addon of its own,
it's more likely the dispatcher as it exists now will dissapear relatively soon.

this commit also make the loading of plugins a bit more defensive and
informative, if a plugin is configured in a profile but could not be loaded a
warning is printed
