Login Panel should be dynamic with the width of logo

The table width of the login/logout panel doesn't grow with the width of the logo. Please look at the screenshot for more details.

A customer request:

From Christoph,
>My question refers to the kind of pages like logout, login, administrator and so on.
>If you use a company logo wider than the table width on these pages, the table width doesn't grow centered with the logo width dynamically.
>So you get an unbeautiful Screen.
