Title: only warn if entities are not included

currently it warns when they are blank, too.

but it's perfectly valid to have a tweet with no entities;

``` json
{
"created_at":"Fri Feb 07 12:01:45 +0000 2014",
"id":431759687642787841,
"id_str":"431759687642787841",
"text":"Getting trains around the UK is absolutely extortionate. It never ceases to amaze and disgust me.",
"entities":{
"hashtags":[],
"symbols":[],
"urls":[],
"user_mentions":[]
}
}
```
