Bug 27099: Stage for import button not showing up

In the latest version of Chrome, pages where the Humansmg library is
included have a problem where the language footer obscures the bottom of
the page.

The problem traces back to some CSS in the Humanmsg library's CSS file:

html, body {
    height: 100%; /* Damn you IE! */
}

Removing the line doesn't have any ill effects that I can see in Chrome
or Firefox, and it fixes the problem in Chrome. IE can be damned.

To test you must have one or more translations enabled in the staff
interface.

- Apply the patch and clear your browser cache if necessary.
- View pages in the staff interface which use the Humansmg library,
  e.g.:
  - Administration -> System preferences. Choose a category of
    preferences which will be numerous enough to require scrolling to
    reach the bottom of the page.
  - Tools -> Stage MARC records for import. Upload a file to display the
    form for staging the import.
  - Cataloging -> Advanced MARC editor

On each page the language footer should not obscure the bottom of the
page.
