Sentence Dectector is still using the OpenNLP 1.4 mechanism of loading it's model file.
a. Suggestion: Let's update it to use the new 1.5 way similar to POSTagger.
- Remove non longer required classes: SuffixMaxentModelResourceImpl, MaxentModelResource, SuffixSensitiveGISModelReader, classes etc.

There may have been a performance reason for shared resources, but this is a tiny model compared to the others, and it's only done once during init time. This should simplify the code and it's references significantly.
