Fix grammar & link in readme, changed title of HTML5 logo so it's easier to read

`Readme.md`:
- Unconscious :arrow_right: Subconscious

I doubt you did this while unconscious :laughing:
- Added link to `maxogden` since for some reason it doesn't automatically link

`Index.html`:
- `... Device Access, Performance & Integration, Semantics, and Offline & Storage` 

Seems less readable than:
- `... Device Access, Performance & Integration, Offline & Storage, and Semantics` to me.
