improve doc on how to run app in development

[Kleak]

I'm trying to write a little app with butterfly but i think there is a piece that is missing right now because i have to restart the dev server every time i do a change.
And some part of the app are not working like eventListener

So i think improving the documentation for newcomer is a good starting point.

If someone can explain here how to run an app i will write a doc about that for newcomers

VM-based dev mode is still too buggy. However, as of 2 minutes ago you should be able to use DDC with butterfly now:

pub serve --web-compiler=dartdevc
