[Owncloud] File upload broken after commit 4374d55

[Daniel Köb]

Hi,

With the updated local permission checks the file upload is broken. It
tries to check if the new file can be written. But is_writeable returns
false for a file that does not exist yet. Thus, on uploading files the
is_writable check has to be made on the containing directory.

Furthermore, the web UI does not provide any feedback. Instead the
upload seems to work normally, although the progress indicator never
goes away. After a reload the file is just not there. It would be nice
to get some feedback if is_writable returns false (even on the
containing directory).
