pesky progress frame and docker progress styling

I needed to modify a couple files outside of our dynamix repo.  These changes complement commit b4b5527

Here are the two files in question:
- /usr/local/emhttp/logging.htm
- /usr/local/emhttp/update.htm

In each of those files, please add the following line right after the `<script>` tag:
`parent.document.getElementById('progressFrame').style.zIndex = 10;`
