Admin menu allow to be shown by default

Add this in your CSS, that way it works the way it was suppose to even if "hide by default" was not checked...

body.adm_menu_hidden #admin-menu {
  display: none;
}

I noticed that there is a CSS file with the module... That means that the code must be added to admin_menu_drop.css and this is not a fix situation, but incomplete code. ALSO, the css that is there isn't correct either and has no effect. The heiarchy of CSS also depends on the complexity of the selector hence overwriting the margin-top body.adm_menu_hidden has no effect and must be body.admin-menu.adm_menu_hidden. Its a full rewrite, so I'm not attaching a patch. Please review:

admin_menu_drop.css

/* $Id$ */

body.admin-menu.adm_menu_hidden {
  margin-top:0px !important;
}
body.adm_menu_hidden #admin-menu {
  display: none;
}

The fix in #3 works as expected.
It includes two components.
The correction to the existing css file is a duplicate of #2047537: Body margin did got get reset properly

The fix from #2 works for when the configuration "hide by default" box is not checked, allowing the menu to be shown as default.

I have changed the title to reflect what this fix actually doing.

Here is the fix rolled as a patch against the current 7.x-3.x branch
