Use local eslint when available

[SebastienElet]

When you work on a project with eslint as dev-dependency, it's better to use it instead of using global one.

I use the fallowing vimL to do the job :

let g:local_eslint = finddir('node_modules', '.;') . '/.bin/eslint'
if matchstr(local_eslint, "^\/\\w") == ''
    let g:local_eslint = getcwd() . "/" . local_eslint
endif
if executable(local_eslint)
    let g:syntastic_javascript_eslint_exec = local_eslint
endif

hello @SebastienElet , I think this is better when node_modules are nested.

" get eslintrc path
let eslintrcpath = findfile('.eslintrc', '.;')
autocmd FileType javascript let b:syntastic_checkers = eslintrcpath != '' ? ['eslint'] : ['jshint']
" find eslint beside eslintrcpath
let local_eslint = substitute(eslintrcpath, ".eslintrc", "", "") . "node_modules" . '/.bin/eslint'
if executable(local_eslint)
    let g:syntastic_javascript_eslint_exec = local_eslint
endif

@SebastienElet I think you should only need to update the env PATH to use ./node_modules/.bin.

export PATH=./node_modules/.bin:$PATH;

It will works for any editor or project you use.
