Switching to settingslogic to manage our configuration. THE FILE FORMAT HAS CHANGED. OLD APP.YML AND APP_CONFIG.YML FILES WILL NOT WORK ANYMORE.
Two important differences:
1. The app only looks in one file for settings: config/application.yml. If you want to override something, do it in that file. It is gitignore'd. If config/application.yml does not exist, or exists but is in the old format, you'll get a nice friendly set of instructions on how to convert your old file.
2. script/server settings are no longer in application.yml. They have their own settings file - copy config/script_server_config.yml.example to config/script_server_config.yml. This is also gitignore'd. script/server will print a message and exit if that file doesn't exist.

This reverts commit eddd8d96.

This reverts commit 8ee81314.

Use standard carrierwave gem instead of deleted git repo. This may break photo uploading, but better that than breaking bundle install.
