Add debian folder

i moved everything to the folder src and added the debian and data folder for the packaging stuff. i also added the unicorn.conf.rb file...
the package is called guh-rails 
    
    apt-get install guh-rails
    
unicorn you can start with 
    
    service unicorn start
    
currently, the worker needs ~1min to start...can this be improoved? 

ps: currently you need to start guh as
    
    guhd
    
the guhd daemon still has a bug (cpu at 100%).
