delete the test/dummy directory
ignore the spec/dummy directory where we will create the
dummy app for each test run
add gems to test the application
add the install generator (commented out migration code since no migrations)
added rake task for create the spec/dummy app
added travis setup - relies on rake setup_dummy_app
1 test to ensure that testing infrastructure works
postgres had trouble recreating indexes (dublicate indexes) therefore
just go with mysql for now.
Merge pull request #1 from westonplatter/rspec_travis

setup rspec, dynamic dummy app creation, and travis mysql support
