[Owncloud] StatusDialog use of QListView::activated signal

[owncloud_mailing_list at status.e4ward.com]

Hello all.

The StatusDialog class uses the QListView::activated() signal (inherited 
from QAbstractItemView) to determine the state of the Enable/Pause 
buttons etc. According to the docs:

"How to activate items depends on the platform; e.g., by single- or 
double-clicking the item, or by pressing the Return or Enter key when 
the item is current."

I'm on Ubuntu 12.04 64-bit, using Qt 4.8.1, and this signal is not 
thrown if I click on the folder. It's only thrown if I select a folder 
and press enter, or if I double-click (which serves another purpose as 
well-- opening the folders). I don't think this is working as desired. 
Is there a reason this isn't simply using the QListView::clicked() signal?

I would like to write a patch for this, but I want to know if there was 
a good reason for using activated(). If it was for compatibility with 
other devices, perhaps this should using a selection model instead?

Please let me know so I can continue.
