Consolidate most "BookReaderJSSimple" demo files

Most of the demo files differ only in:

1. `plugins` used
2. BookReader options
3. Book data

All the demos that use BookReaderJSSimple have the same data. Consolidate those to be the same HTML file, with URL parameters for specifying any extra BookReader options.

## Summary of Requirements
- [ ] Create a demo file with URL parameters:
- [ ] e.g. `&plugins=mobile_nave,url,tts`
- [ ] e.g. `&extraOpts={"startFullscreen": true}`
- [ ] Most demos including `BookReaderJSSimple` consolidated.
