hopefully this will fix the ascii issue in 1.9.3
initial post model tests pass
slight aesthetic modification of secret_key_base
added hashify gem
added config to spew SQL to STDOUT
removed deprecated config options
updated posts_tags migration to check for the table if it exists
updated .gitignore, and added acts_as_sane_tree to Gemfile
renamed parent column on posts table to parent_id, installed awesome_print gem
removed awesome_print, doesn't seem to actually do anything
Comments work.  This resolves #34
