Added a heading "editing page" in page editor for visual appeal; removed use of alternate <?= ?> syntax in installer as it was causing problems on Win2k3 + PHP/FastCGI. (Experimentally using TortoiseHG's hgtk to commit)
tinyMCE.addI18n('en.advhr_dlg',{
width:"Width",
size:"Height",
noshade:"No shadow"
});
