Autocompletion breaks after dot

[viktorasl]

First of all, great plugin! Saves lots of time. But there is a slight bug with autocompletion:
Having key some.complex.key.in.table and trying to type NSLocalizedStringFromTable(some autocompletion shows the suggestions, but after putting "." everything disappear. I hope it will not take much time to fix, because having lots of keys with prefix some gets harder to autocomplete.
