Update libraries.txt

Added jQuery 2.0.0, AngularJS 1.0.6, webfont 1.4.2
Changed jQueryUi 1.8.3 to 1.8.4, because as google write it: "note: This library depends on jQuery. You must also load jQuery before loading this module. Version 1.8.3 is not hosted due to its short life, and the alias 1.8.3 actually loads 1.8.4."
