Look for a local flow-bin

[ryyppy]

I always wanted to tackle this, so I might as well create an issue here...
The Vim-Plugin should initially look if there is a node_modules/.bin/flow binary, before trying to use the globally installed one.

[SeeThruHead]

"Use locally installed flow
let local_flow = finddir('node_modules', '.;') . '/.bin/flow'
if matchstr(local_flow, "^\/\\w") == ''
    let local_flow= getcwd() . "/" . local_flow
endif
if executable(local_flow)
  let g:flow#flowpath = local_flow
endif

i tried copying over what I have that works for eslint, flow is now showing per project flow errors in my quickfix

Nice one @SeeThruHead!

[ryyppy]

Cool, works like a charm! Not sure if I should close this issue now... IMO this could be part of the README?

@ryyppy Would be nice to have this as a opt-out setting, since it seems to be the expected default behavior?

[ingocraft]

works for me.
