UIDocumentInteractionController: Make it open more filetypes

[alexschomb]

I know uploading has not yet been implemented at all, so this is just a request for the future. Could you implement the SparkleShare app to open more files? My knowledge concerning iOS development is very limited, but maybe the following explanation by tallerthenyou could help a bit: MiniKeePass/MiniKeePass#59

I would LOVE to see this feature. Dropbox is neat and all, but I would prefer to be in charge of my own host when it comes to sensitive files such as password databases, and sparkleshare seems like a really nice way to do that if we can get something like this working.
