View decrypted Dropbox files without having to export them

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Choose EncFS root on your Dropbox
2. A file browser with decrypted file names pops up
3. This browser doesn't allow you to directly view your files. You'll have to 
export them first.

What is the expected output? What do you see instead?
It would be nice if you could choose to view decrypted files directly without 
having to export them.

What version of the product are you using? On what operating system?

Please provide any additional information below.

Not sure how to implement both export and viewing functionality in the file 
browser. Maybe pressing a file name (rather than a checkbox) will pop up a 
dialog that offers to export or view the file?

Related to this issue, it would be good to avoid persistent storage of files 
that are only viewed, but not exported; see

As of version 0.0.10, a basic implementation is completed. Long-press file in 
file browser to open directly. Please test.

As of yet, decrypted volumes can't be re-opened. Instead, they have to be 
re-decrypted from scratch, which is quite tedious. It would be good to separate 
the decryption from the file browsing part now that we can directly open files 
without having to export them first.

It doesn't work for me: when I try to open a text file, I get an error saying 
that it's not a valid PDF file. Cryptonite should ask to select an application 
/ text viewer to open the file (like BoxCryptor does).

Thanks for testing. Does your text file have an extension?

No, it doesn't have any extension.

There's been some progress in 0.0.11, but several issues remain:

* Built-in MIME detection support  for files without extensions is pathetic on 
Android. At the moment, we'll fall back to text/plain in most cases if there's 
no extension. We may have to resort to a 3rd-party mime detection library on 
the long run.
* Some programs can't handle the URI format and/or the file permissions and 
won't open the files. Notable viewers that do _not_ work include the Gallery 
and the DB Text editor.
* Decrypted files are stored in a temporary folder and will only be deleted 
when the decryption is cleared or when the program is restarted.

Let me know if this works for you. Thanks again for testing.
