Banners were not been shown in certain pages; now
they are.
Spec to check if the banner is been shown correctly
added. Before it was in admins specs, now it has it's
own spec out of admins folder.
* Delete all things related to banner images and styles (in code)
* Add a new test to check that the banner is showing correctly
* Update the specs accordingly to match the changes
Update dev_seed to set a random background_color and a font_color for banners (and remove everything about image and style)
Add a rake task to migrate the banner style to backgroun_color and font_color (so that the banners have the same colors than before)
Banner sections can be saved (one banner can appear in several sections)
If the hex color is changed in the textfield, the color of the color picker changes.
Add the admin UI needed to restore the hidden proposal notifications
when hidden by moderator. The admin can restore them or confirm
the moderation made by moderator, just like proposals.
The little menu with the hide notification link and block user link
has been added to each proposal notification.
JS for adding the fade efect has also been added.
There's a flaky test creating a group for a budget which takes place
because toggling a form using jQuery sometimes results in the button not
being correctly clicked by Capybara.
Checking the page with `expect(page).to have_button 'Create group'`
before clicking the button doesn't solve the problem; it looks like in
those cases Capybara waits for AJAX requests but not for JavaScript
animations.
See also issue #2573.
The select button seems to be outside the window. Removing some columns
to make the select button visible by capybara
This is just a temporary fix, we have to find a better solution.
Playing with the css to find an appropriate length for the table
containing this select button, is probably the way to go
