Change Processor File / class names

[JRMeyer]

Hi Oliver et al,

I was looking up some things on SKLDecisionTreePausePredictor, because the SKL part wasn't obvious to me. Then I saw it's sci-kit learn, and that there's a file called SKLProcessors.py with other processors built on sci-kit learn.

I suggest the SKL be removed from class and file names, to make things more transparent.

In general, it seems that the *.py scripts in $OSSIAN/scripts/processors/* are one processor per file. (e.g. PhraseMaker.py, VSMTagger.py, Syllabifier.py).

SKLProcessors.py deviates from this trend, with multiple processors contained in the one file. I suggest that some kind of standard for processors and their filenames be set.

Maybe stick with the one processor per python script?

Thoughts?
