OutOfMemoryError when viewing large files in admin

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Upload a large ZIP file. We are uploading a ~9MB file
2. Browse to the file in admin, /cms/file.vm

What is the expected output? 
Form to edit the file metadata with editable field filled and display an 
external link (btw, typo in admin: "Exrernal"). 

What do you see instead?
Empty Title and Name filed, no metadata or external link. 
Error message:
Alert! Can't connect to server. Error: Internal Server Error Internal Server 
Error 500 undefined

Here is a patch. Basically we only serialize the content to JSON if the file is 
a text file.
