Add support for ink-language-server

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.

+
+  Dictionary containing configuration settings that will be passed to the
+  language server at startup. For certain platforms and certain story
+  structures, the defaults will suffice. However, many projects will need to
+  change these settings - see the ink-language-server website for more
+  information.
+
+  An example of setting non-default options:
+		{
+		\  'ink': {
+		\    'mainStoryPath': 'init.ink',
+		\    'inklecateExecutablePath': '/usr/local/bin/inklecate',
+		\    'runThroughMono': v:false
+		\  }
+		\}
