This commit also introduces a new CSSEvents object that is used to
abstract vendor specifics events related to CSS transitions and
animations.
Fixes#183.
Fixes#179.
The user is now able to upload an avatar, and pick one in a list.
This functionality should eventually be abstracted in a community
package but we still need to work on a great public API. We rely on
collectionFS to manage uploaded avatars. We also removed
bengott:avatar which was trying to solve the wrong problem (namely
displaying the avatar, which is as simple as displaying an image), and
not a avatar system as it should be.
Gravatar support is coming (back) soon. We may also want to have a
list of default fun avatars the user can choose instead of uploading
its own one.
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.
