UI Updates

This pull request makes the following changes:

* The posting popup window now displays the browser's address bar. Without the address bar or displaying the glyph, it is possible for websites to spoof the popup window. This is a temporary measure until the anti-spoofing glyph can be improved.
* Moved the pages directory to bootstrap3. I made this change so we could use the new glyph icons in a new popup view.
* Made the modal button show a popup menu. This allows users to access the privly-applications bundle without needing to open the options window first.
* Updated the Privly applications module.
