Really minor fixes

[clochix]

• CSS fixes to add a scrollbar to the modal window used to select contacts for sharing. If we select a lot of contacts, the list was grouwing outside the window, whose max height is fixed;
• fix a template, removing a parenthesis inside the name of the default image;

The problem with overflow is that you can't see the auto-complete widget when it's on. I don't know how to handle both cases.

Another try to fix the overflow problem, seems to work for me, would you mind to give it a try?

Here is my feedback:

• Putting loading image as a background was a bad idea: it doesn't work well with PNG (transparent background).
• The loading image is displayed on hover in the album item list.

• I now remove the background image once image is loaded;
• fixed the :hover bug;

The photo loading progress bar is broken. I can't merge this PR. I wait for your fix.

Thank you, it works fine.
