Add "Application" for Helping Users Select an Application

* Added: I added an application that attempts to summarize the privacy properties of the different applications. You can navigate to the page in the "new link" drop down menu.
* Improves: I added Twitter Bootstrap icons to all the things. The things look better now.
* Improves: I made the build script more DRY.
* Improves: I set the logout link to redirect the user to the login page instead of reloading the current application.
* Resolves: This pull request resolves an issue where the ZeroBin app's tooltip incorrectly said content is not editable.
