This PR removes a leftover `dbg!` from `styleable_helpers!`.

We already removed this in the `gpui2-ui` branch, but getting this on
`main` since @KCaverly pointed it out.

Release Notes:

- N/A

Adding a few bindings to bring first class feeling multiselect to zed's
vim emulation.

gn and gN are similar to similar vim bindings, ga is similar to gA (and
I doubt we need vim's real ga), g> and g< are just made up.

Release Notes:

- vim: `g n` / `g N` to select next/previous
- vim: `g >` / `g <` to skip current selection and select next/previous
- vim: `g a` to select all

- g n / g N to select next/previous
- g > / g < to select next/previous replacing current
- g a to select all matches

This fixes several bugs with how spaces and keyboard commands interact
with channel creating / renaming.

Release Notes:

- Allow cmd-+ in addition to cmd-= for zoom in
([#1021](https://github.com/zed-industries/community/issues/1021)).

Although I had initially thought this was something more to do with
option key handling, it turns out to be a straightforward and reasonable
feature request.

If we're closing items we should not be writing files that have not
changed (e.g. empty untitled buffers)

Release Notes:

- vim: Add v1 of command mode
([#279](https://github.com/zed-industries/community/issues/279)). The
goal was to cover 90% of what most people actually do, but it is very
incomplete. Known omissions are that ranges cannot be specified (except
that `:%s//` must always specify the % range), commands cannot take
arguments (you can `:w` but not `:w [file]`), and there is no history.
Please file feature requests on
https://github.com/zed-industries/community as you notice things that
could be better.
- `:` triggers zed's command palette. If you type a known vim command it
will run it, otherwise you get zed's normal fuzzy search. For this
release supported commands are limited to:
- - `:w[rite][!]`, `:wq[!]`, `:q[uit][!]`, `:wa[ll][!]`, `:wqa[ll][!]`,
`:qa[ll][!]`, `:[e]x[it][!]`, `:up[date]` to save/close tab(s) and
pane(s).
- - `:cq` to quit completely.
- - `:vs[plit]`, `:sp[lit]` to split vertically/horizontally
- - `:new`, `:vne[w]` to create a new file in a new pane above or to the
left
- - `:tabedit`, `:tabnew` to create a new file in a new tab.
- - `:tabn[ext]`, `:tabp[rev]` to go to previous/next tabs
- - `:tabc[lose]` to close tabs
- - `:cn[ext]`, `:cp[rev]`, `:ln[ext]`, `:lp[rev]` to go to the
next/prev diagnostics.
- - `:cc`, `:ll` to open the errors page
- - `:<number>` to jump to a line number.
- - `:$` to jump to end of file
- - `:%s/foo/bar/` (note that /g is always implied, the range must
always be %, and zed uses different regex syntax to vim)
- - `:/foo` and `:?foo` to jump to next/prev line matching foo
- - `:j[oin]`, to join the current line (no range is yet supported)
- - `:d[elete][l][p]`, to delete the current line (no range is yet
supported)
- - `:s[ort] [i]` to sort the current selection (case-insensitively)
- vim: Add `ctrl-w o` (closes everything except the current item) and
`ctrl-w n` (creates a new file in the pane above).
([#1884](https://github.com/zed-industries/community/issues/1884))
- all: Add a "Discard" option to prompt when saving a file with
conflicts (previously this only appeared on close, not on save).

Internal changes:
- The Picker will now wait for pending queries before confirming (to
handle people typing `: w enter` rapidly.
- workspace::save_item and Pane::save_item are now merged together, and
the behavior controlled by `workspace::SaveIntent`.
- Many actions related to closing/saving items now take an optional
`SaveIntent`.

This reverts commit 5c75450a77b0579649bbf79365c9cef5a2c1110f.

This is a PR I built for a friend of a friend at StrangeLoop, who is
making a much better LSP for elixir that elixir folks want to experiment
with. This PR also improves the our debug log viewer to handle LSP
restarts.

TODO:
- [ ] Make sure NextLS binary loading works.

Release Notes:

- Added support for the experimental Next LS for Elxir, to enable it add
the following field to your settings to enable:

```json
"elixir": {
    "next": "on"
}
```

Release Notes:

- Fixed clicking a code action only ever performing the first action in
the list rather than the one clicked on.
