add "type" parameter which defines what type to convert the value

Example:
J48's confidenceFactor is float, but Python uses double

The following converts the string "0.3" into a float before setting the property:
cls = Classifier("weka.classifiers.trees.J48")
cls.set_property("confidenceFactor", "0.3", "f")

this only seems to be a problem for Java "float" primitives

added function "double_to_float" to weka.core.types module that generates a java.lang.Float object from a Python double
