Add server properties in documentation

[oscarr-reyes]

i have seen in diet-static example that uses path to get the directory of the application.. but i don't see this kind of information in the documentation..

there should be a section that shows all the properties available in diet server

You are right :) I just updated the docs:
http://dietjs.com/api/server#app.path

Thanks,
Adam
