LPS-44707 - Language icons overflow when many locales enabled (input localization)

Hi @jonmak08,

Attached is an update for https://issues.liferay.com/browse/LPS-44707.

This one is also very related to the pull I sent you for https://issues.liferay.com/browse/AUI-1256 (https://github.com/jonmak08/alloy-ui/pull/109).

The alloy fix would resolve the issue described in LPS-44707 on it's own, but Nate had said that he would like to also change the input_localized taglib flags from being a table to a list.  I went ahead and did that and adjusted the CSS accordingly.

Note:
I ran into an issue where, on page load in some browsers, the list of flags was first appearing unstyled for a second, and then quickly changing to the correct style.   In order to prevent this I had to apply an inline style ```display: inline-block``` to the ```LI``` elements.

Please let me know if there are any issues.

Thanks!
