Changed Content Manager Folder

Changed the content manager to "en" so that the url is shorter to get to
the main dashboard
Changed The Logo

Fixed the redirect to the new folder "en/index.php". Also adjusted the
logo image inside the dashboard
MAJOR CHANGES

I made changes to all the directories. Stylesheets are going to in the
en/ folder. I left the login stylesheets in the top directory. I also
got the javascript working again. I added a reports page and an invoice
page.
