The main point of this change is to streamline the core
code for input pills, and we use also modify user groups.
The main change to input_pill.js is that you now
configure a function called `create_item_from_text`, and
that can return an arbitrary object, and it just needs
a field called `display_value`.
Other changes:
* You now call `input.create(opts)` to create the
widget.
* There is no longer a cache, because we can
write smarter code in typeahead `source` functions
that exclude ids up front.
* There is no value/optinalKey complexity, because
the calling code can supply arbitrary objects and
do their own external data management on the pill
items.
* We eliminate `prependPill`.
* We eliminate `data`, `keys`, and `values`, and just
have `items`.
This allows for pasting in comma separated lists that will validate
pills on paste, along with creating an API for inserting many pills.
This now allows in the `input_pill.pill.append` a comma separated list
that will then call the `insertManyPills` method that will break up the
input and then call `append`.
The function should execute initially and return a function, not
be a function that when executed returns another function. This
fixes an existing bug.
Some of the calls in our codebase will call for the `.keys()` method a
lot, so this caches the results and returns them rather than mapping
the array if it knows the state to be the same as before.
If a user clicks on the pill container and not directly on a pill
or on an "x" inside of a pill, it should be presumed they are
trying to input new text. This effectively makes the whole non-pill
section an input bar.
