The UI and the internal APIs are still rough around the edges but the
feature is basically working. You can now select multiple cards and
move them together or (un|)assign them a label.
* Implement visibility choice on board creation;
* Rework the board header bar. Remove links to un-implemented
features;
* Implement a board star counter (visible if the board have >2 stars);
* Define a new icon (a thin cross) to close elements;
* Remove $(document).on('mouseover') event handlers that were
basically fired hundreds of times for nothing, we now define a proper
Tracker dependency to execute jquery-ui plugin initialization only
when something has changed;
* Bug fixes related to list scrolling.
The new EscapeActions object decide what to do when the user press the
Escape key (such as closing a opened popup or inlined form).
This commit also re-introduced the sidebar current view as a sidebar
component local state.
The idea is that by displaying card details in a sidebar stuck on the
right of the screen, the mouse had to travel too much before
interacting with it. I also don’t want to use the Trello solution
(modal) on big screens, because I like the ability to interact with
the selected card and with the board at the same time (like in a
e-mail client).
The solution introduced in this commit consist of opening the card
detail in a column next to the minicard list.
This commit also fix right sidebar members and labels drag and drop.
