Updated to Bootstrap 3.0.3 release (proper)

Updated to Bootstrap 3.0.3 based on source package from getbootstrap.com (release on 5 December 2013); also checked that the main/static/font/ based Glyphicons fonts didn't change this time (see #33 experience).

Note that this Pull Request full replaces the previous #45 "Updated to Bootstrap 3.0.3 release" PR.
