User:Tpt/Upload Wizard

I have written for the codding challenge a beginning of an upload wizard for the Android Wikipedia app. This wizard is a port of the desktop one adapted to mobile size and native app. This is only a begging. I have a very few time, I don't know if I have time to finish it.

The code of these modifications is available here. Here is the fist commit.

Bugs
This is only a beginning. Expand the list.
 * Don't show a wait widget during uploading.
 * Upload of big files crash on 3G connection.
