Bare minimum Mac OS X standard features

[snoblenet]

Which operating system does the issue occur on? 10.13.1

Great job.

I love that the UI leaves the keys unmapped, so I can map them myself with ease within Neovim. (Which is now so good at window/scrollback/etc management that I won't need Tmux.)

Four features that I think are a 'must have' on the Mac for the 1.0 release, however:

• A double-clickable installer for the app
• A Homebrew installer for the command line tool
• Documentation for sending flags to the command line tool, so we can create Automator apps that, say, open any file dragged onto them in Neovim in Alacritty
• Remember/restore window size and location between quitting and relaunching

One more thing that doesn't work on macos right now is auto-switching to keyboard layout that was used in the alacritty (option "Automatically switch to a document's input source" http://www.tech-recipes.com/rx/53194/os-x-switch-language-input-sources-automatically/). So if I work in alacritty using US layout and change focus to app with non-us layout then back to alacritty the non-us layout will stay.

@kalekseev @jwilm Mind if I create the separate issue of the comment above? I can take a look and try fixing that

@zindel I created an issue about that in glutin rust-windowing/glutin#961 would appreciate if you fix that
