Omni completion source for asyncomplete.vim

Plug 'prabirshrestha/asyncomplete.vim'
Plug 'yami-beta/asyncomplete-omni.vim'

call asyncomplete#register_source(asyncomplete#sources#omni#get_source_options({
\ 'name': 'omni',
\ 'whitelist': ['*'],
\ 'blacklist': ['html'],
\ 'completor': function('asyncomplete#sources#omni#completor')
\  }))

If omnifunc change cursor position, asyncomplete-omni.vim does not work correctly.

For example, HTML is blacklisted above because Vim's default omnifunc repositions the cursor leading to quirky behaviour. You can reenable if you are using a more appropriate omnifunc.
