Prettify v1.0

Major
 - Added Font Awesome and updated buttons with icons
 - Renamed poorly-named "Endpoint Configuration" to "Endpoint Package Manager"
 - Moved "Show/Hide Brand/Models" from "Advanced Settings" to "Endpoint Package Manager"
 - Restructured most layouts to confirm to FreePBX look-and-feel

Minor
 - Updated header on each page so the user knows where they are (I would constantly get lost and yell, _"What friggen page am I on? How did I get here? Where are my pants?"_)
 - Seemlessly integrated custom OUIs into full list
 - Colorized buttons under new Package Manager for ease of idenification
 - Numerous style-edits for maximum sexiness
 - Added i18n translation for existing words in dictionary
