ms-upgrade-site.php upgrades sites without feedback in case of errors

[Denis-de-Bernardy]

the screen uses setTimeout( "nextpage()", 250 ); to go through sites five by five.

two problems:

1. the timeout may be too short to upgrade some sites

2. in the event any errors occur, you get absolute zero feedback

the screen should do the upgrades in an iframe, and create new iframes as needed when errors occur.
