Replace the old (and broken) jshint + jscsrc by eslint and configure
it to support some of the ES6 features.
The command `eslint` currently has one error which is a bug that was
discovered by its static analysis and should be fixed (usage of a
dead object).
This new draft saving system is currently only implemented for the
card description and comment. We need better a component
inheritance/composition model to support this for all editable fields.
Fixes#186
Motivations:
* Iron-Router foces us to use Tracker.nonreactive black magic in order
to avoid un-necessary re-renders;
* There is a community consensus (supported by some MDG members) that
the flow-router API is easier to reason about;
* The useraccounts now supports flow router (that was a blocking
element when I considered the switch ~3months ago)
On the server we use the Picker router, as encouraged by the Kadira
team (which develop both Flow and Picker routers).
In the current state of things there are some bugs related to the
missing Loading architecure. Previously onRendered callback where
always called when the data the component needed was available, now
we have to handle this ourselves, which we will in a following commit.
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.
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.
