btn-lg is smaller than input-lg

In Chrome, Safari, and Firefox (not IE10+) btn-lg is a pixel off and should be 46px but instead its 45px. Here is [some code](http://plnkr.co/edit/zS4bT68QREkpOTaImqEX?p=preview) that I'm working with. What I've done in my projects is just add a height:46px to btn-lg but I think a better solution is to just change the @line-height-large to 1.34 instead of 1.33.
