Update to Bootstrap 3.3.5

Main benefits of the two versions jumped below

3.3.5:
Updated to Normalize.css v3.0.3.
Updated main in bower.json to comply with recent update to the bower.json specification
List groups now support <button> elements.
Cleaned up some extraneous padding on jumbotrons across various viewports.
Fixed input group sizing classes on all supported elements for real this time.
Applied a few tooltip and popover positioning fixes.
Fixed behavior when using tooltips and popovers that are triggered by multiple events.
Fixed some memory leakage in the tooltip and popover plugins.
Fixed incorrect Affix positioning when a webpage has a sticky footer.
Fixed npm package to include all Grunt scripts, so that grunt dist works if you installed Bootstrap from npm.

3.3.4:
Fixes for a few significant bugs in the Modal plugin.
Fixes for a couple annoying bugs in the ScrollSpy plugin.
Bootstrap is now also available as a Meteor package in the Atmosphere package index.
Convenience aliases have been added for currency symbol Glyphicons based on their related 3-letter ISO currency codes. For example, .glyphicon-rub is a new alias for .glyphicon-ruble, the currency symbol for the Russian ruble (RUB).
We have deployed AnchorJS in our documentation to make it easier to link to specific sections within the docs.
