Subject: [PATCH] fix word count

Fixes incorrect word count.

The current implementation adds a period to the end of any text, which adds an extra word count to any phrase.  Taking an example from https://github.com/cgiffard/TextStatistics.js/issues/4 for instance:
```
var stats = textstatistics("monkey goes yay");
stats.wordCount();
4
```
