responsive .hidden-* classes change from display block to inline-block

Created by: jholl

related to issues #8500 , #7808 (closed) , #4929 (closed) ; using .hidden-sm to hide span within .nav > li > a . Because class is display: block above -sm then text wraps to new line. Would you consider .hidden-* classes to be display: inline-block instead ?

Here's a jsfiddle of the two cases - but the repercussions could be greater outside of this situation so probably needs more consideration... http://jsfiddle.net/jholl/P86yf/
