Improve dialogue when using the Android file manager, selecting a file and sending it to owncloud: add directory name and a cancel button

[Wikinaut]

When you use the file manager and select "send to owncloud", the owncloud client shows the folders on the server. You then select one of them.

So far, it's understandable.

But the next screen is almost empty, shows only a button at the bottom labelled "upload" ("Hochladen").

I suggest the following GUI improvement:

Implement at this stage a dialogue like:

Upload to <selected directory> ?
Yes or Cancel

is of course the directory which was selected in the previous step. Cancel would go back to the selection window.
