1. Add ale.setup and ale.setup.buffer for pure Lua configuration.
2. Update many global settings to use Booleans instead of numbers to
make types easiert to work with in Lua.
3. Radically reformat documentation and fix errors to make
documentation more usable for Neovim users.
This commit add support for ink-language-server, which it does by
largely copying and pasting from the pure-language-server PR that was
merged recently.
The most interesting things to note are:
- ink-language-server is distributed upstream via npm, which is why we
search through node_modules
- With some coaxing, it can be installed globally - which is why we
search for a global binary.
- Ink is a funky language, and users will likely need to add
initialization options.
- I am not incredibly familiar with vimscript; and I may not have done
some of the buffer searching correctly.
