Subject: [PATCH] Ticket #3011: Add attachments/uploads and
 attachments/file_quota to api/statusnet/config.(xml|json)

file_quota is adjusted from the defined value to take into account the maximum upload size limits in PHP, or cropped to 0 if uploads are disabled.
This can be used by client apps to determine maximum size for an attachment.
