New styles for jquerymobile.com theme

Been working on the new styling for jquerymobile.com for a while now.  Need to get these styles into master as others are now working on the new site and it's a pain to get them to switch their jquery-wp-content to the jquerymobile.com branch. 

I updated the styles and it's been a while since it merged with master.  Just before creating this PR I did a 

```
git rebase upstream/master
```

when I did that all the commits from master came into this branch and now show in the PR.  Please let me know if this was the right way to do this or if I need to do this another way. 

Also I don't have access to push my changes back up to the jquerymobile.com branch in the main repo. 

Thanks
Ralph
