Modify chefignore to ignore more files by default (basically made it the same as the file that is automatically generated by the starter kit found at 'https://preview.opscode.com/organizations'
Added an initial knife.rb and SAMPLE.knife.local.rb...  Basically set all of the defaults and add comments for other more common options...

knife.local.rb based on suggestion from: http://jtimberman.housepub.org/blog/2013/02/01/local-only-knife-configuration
