Made homomorphic to Humanhash.py

Modified algorithm so that outputs match humanhash.py given any input.
Editted default wordlist accordingly.
Also added the "compress" and "uuid" methods found in humanhash.py .
To more closely match humanhash.py, the module now defines a constructor
"HumanHasher" which must be instantiated. ie:
```javascript
var HumanHash = new HumanHasher();
HumanHash.humanize('7528880a986c40e78c38115e640da2a1');
// 'three-georgia-xray-jig'
```
