This is an experiment about the implications of ES6 transpilation in
our code base.
We should also define a new ES6 style guide and a jsHint
configuration, for instance semi-colons are automatically inserted at
the end of lines, so we may remove them. We also need to figure which
ES6 features we want to use, currently I have followed Meteor-core
guidance which is reasonable.
Fixes the data context on the member popover in the details pane. Also
change the way Popover detect if the click is initiated from a parent
popover -- from reading Blaze context, to looking at the event target
parents.
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.
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.
