Fix empties

This adds logic to fix some required fields not being set.

It also bumps the version.

Add entity type

This uses the information available to the communication to set mention and entity types.
The algorithm is heuristic, but does reasonable things.

The following description of the algorithm is taken primarily from the comments. @twolfe, @mgormley do you have thoughts on these heuristics?

### Setting a mention type

A mention's type is the most common non-other NE type for that mention.
This first looks at the NE type for the anchor token of the mention, if given.
If the anchor isn't given, then the span given by the ```TokenRefSequence``` for the mention is used.
The algorithm aggregates over all possible, non-OTHER NE tags for the appropriate "span."
The default return type is "Unknown," which happens

1. if all tokens within the TokenRefSequence are OTHER, or
2. if no NE theories exist, or
3. if the anchor token is OTHER.

### Setting the entity type

The entity type is set to be the type of the representative mention if either
the representative mention is the only mention with a set type, or if the
most frequently seen mention type is the same as the representative mention type.
Otherwise, the entity is assigned type "Other," and a notice is logged.
