Elements of default theme broken in IE7

[coldtrick]

In IE7 the theme has the following issues:

• a white space at the top (loggedin)
• menu items more dropdown has wrong z-index (border of content area title is in front of the drop down)
• menu items more dropdown not very stable
• on members and groups page the sidebar (search by tag) input text runs over the side
• tinymce + embed text above the editor (remove editor, embed content) are not align next to each other
• breadcrumb not showing correctly
• blog (and maybe others too), list mode, edit + like + delete + etc not correctly aligned
• like (thumb) hover not a hand cursor
• delete hover not a hand cursor
• group widgets are have no spacing between the 2 columns

more later...

We should fix some of these before the beta 2 release.

Problems that I've verified:

• menu items more dropdown has wrong z-index (border of content area title is in front of the drop down)
• menu items more dropdown not very stable
• tinymce + embed text above the editor (remove editor, embed content) are not align next to each other
• breadcrumb not showing correctly
• group widgets are have no spacing between the 2 columns

Could definitely use some help fixing the remaining items if anyone's feeling like diving into the wonderful world of IE CSS.

The only outstanding IE 7 problem from this ticket is the site-more menu dropdown.
