Fixed bug in v2.1.1 Navbar. Menu is hidden in IE8 and IE7.
This was caused by removing
overflow: visible \9;
for the collapse class from less/component-animations.less in commit fe3ed433
The commit(fe3ed433) removed a nasty hack for IE7 and IE8 that broke collapsables, but had an unintended side effect on navbar menus.
