Re-brand open-source ShareLaTeX code as 'ShareLaTeX Community Edition'.
The Dropbox and template code has been extracted out into a separate module and removed from the ShareLaTeX Community Edition. There should be no broken features due to lack of open source components now.
Websockets and real-time data now go to a separate light-weight real-time service.
Updated PDF viewer that loads page-by-page for much quicker loading times on large documents.
