Steve Howell 026474921a todo widget: Downgrade error to warning.
We were creating errors for task keys that were
from older versions of the widget.  We don't migrate
data for the widgets yet (they're all still considered
to be somewhat beta); instead, we just drop bad data
on the floor.

Rohitt and I re-tested the widget on czo pretty
extensively to verify that these errors don't show
up for newly created widgets.

Steve Howell de97351b5a todo widget: Simplify idx calculation.
We now only compute idx on the outbound side,
instead of spreading out the responsibility.

We just iterate through all our items to find
the next available number.

Steve Howell eb83b9a960 todo widget: Remove user_id from data structure.
The only place we use the user_id in the todo
widget is in our keys, which prevents duplicate
keys across senders.

Steve Howell 91a37e7237 todo widget: Use a Map to track items.
This is a more natural data structure and
removes the need for `get_task_index`.

Steve Howell b5e6d872e6 todo widget: Rename function to name_in_use().
The name here is a bit more precise, as we're
not checking whether a task exists so much
as whether just a particular name is in use.

We also move the function out of the `check_task`
layer, which feels a bit overkill in terms
of nesting (plus, we're gonna remove the other
function inside of `check_task` soon).

Steve Howell 4eafaf1302 todo widget: Sort items alphabetically.
We still keep pending tasks above unfinished
tasks, but otherwise the sort is alphabetic.

Steve Howell 8c73375f10 todo widget: Avoid completed/pending complexity.
We now only compute these two sublists when we
need them, rather than having to splice and
unshift them every time.

majordwarf 8ea3bfb927 todo_list: Fix list item indexing in race condition.
The todo_widget was using the using a counter to store the key value of
every task. This would cause assiging multiple tasks the same key value
in a race condition. To avoid this we make "sender_id" a part of the key
along with the counter.

Also the `key` now not being a integer value, we can't use it to find the
index of the task using it. Thus, a function is made that will find the
index of task whose key is sent by the user to strike.

majordwarf 68dcdcd28e todo_list: Add task description and index numbers.
The user can pass description along with the task name by splitting the input string with hyphen.

Eg: Task Title - Task Description
todo_list: Add index numbers to task.

Anders Kaseorg 70ff164f89 js: Convert _.any(a, …), _.some(a, …) to a.some(…).
And convert the corresponding function expressions to arrow style
while we’re here.

Anders Kaseorg 28f3dfa284 js: Automatically convert var to let and const in most files.
This commit was originally automatically generated using `tools/lint
--only=eslint --fix`.  It was then modified by tabbott to contain only
changes to a set of files that are unlikely to result in significant
merge conflicts with any open pull request, excluding about 20 files.
His plan is to merge the remaining changes with more precise care,
potentially involving merging parts of conflicting pull requests
before running the `eslint --fix` operation.

Anders Kaseorg d17b577d0c js: Purge useless IIFEs.
With webpack, variables declared in each file are already file-local
(Global variables need to be explicitly exported), so these IIFEs are
no longer needed.
