Use system fixjson if available

[Kamilcuk]

On a distribution it may be possible to install fixjson to native system paths using native system package manager. On these distribution there's no need to call npm.. Just use the native tool.

Please add:

--- i/autoload/fixjson/npm.vim
+++ w/autoload/fixjson/npm.vim
@@ -4,6 +4,9 @@ let s:pathsep = s:is_windows ? '\' : '/'
 let s:cmd_path = join([s:root_dir, 'node_modules', '.bin', 'fixjson'], s:pathsep) 

 function! fixjson#npm#local_command() abort
+       if executable('fixjson')
+               return 'fixjson'
+       endif
     if !filereadable(s:cmd_path)
         call fixjson#npm#install()
     endif

This is just enough so that local command picks fixjson from /usr/bin/fixjson without calling npm.

Please use g:fixjson_executable in your vimrc:

let g:fixjson_executable = 'fixjson'

If you want to use system-installed fixjson only when it is available:

if executable('fixjson')
  let g:fixjson_executable = 'fixjson'
endif

BTW, vim-fixjson already prefers global fixjson command:

Thank you! I am sorry, I totally overlooked that - I missed that in code (I should get more sleep (or more coffee!)). Thank you! Och, I believe it would be great to add even a super short documentation with the list of available g:options, it would help a lot.
