/**
|
|
* GuessContentType addon
|
|
*
|
|
* A lot of the built-in File objects just return application/octet-stream
|
|
* as a content-type by default. This is a problem for some clients, because
|
|
* they expect a correct contenttype.
|
|
*
|
|
* There's really no accurate, fast and portable way to determine the contenttype
|
|
* so this extension does what the rest of the world does, and guesses it based
|
|
* on the file extension.
