fixed #8 - debug restarts server

* fixed debug so it will restart server on file save
* provided for additional watch directories for projects by creating a
debug-watch-directores.coffee in their server path.

# Sublime Text 2 manages to save files without triggering the watcher.
# Go to menu Tools // Build System // New Build System...
# make "cmd"=["touch '$file_path'"] and add ,"shell": true
# save it and set it from the same menu
# Now press <Command>B to save all files and restart your node server
