[request] want support for better control over Tesseract options and features

[RaiMan]

Hi,
I'm using Sikuli 1.0.1 for a script editor application
I use this for any sort of automation, but as soon as I started bot-ing for games I found myself in need to understand Tesseract deeper.
So now I need to use some custom configurations or parameters, but I'm not sure how to do it even using the low level native java wrappers.
From javadoc Vision class has a setParameter method, but the value is float, while some parameter I need to set are strings (white/black lists)
I could config them via a file in tessdata/config but I don't see any method for the config file param. In tesseract documentation this should be inputed in the command line, but I don't know how to provide this to the java class, nor I understand if VisionProxyJNI could be usefull for this.

I would have liked to see the source of Vision class to reimplement what I need, but I can't find the source code on git...
