You can see some new content templates that will work with bootstrap based skins here. You'll need to login to see those. The demo site login is email@example.com and the password is admin
The next release will include a way to import/export content templates. The old templates you're referring to are hardcoded and they require custom CSS to work. It's best if the content templates work based on what the skin can do rather than adding bloat to every skin to support old markup and css coding styles.
