Long and Float values are converted to String when passed to node-lib functions

[aro]

Javascript values that have an underlying value of Java Long or Float, are converted to String when stored in node using nodeLib create or modify functions.

The problem seems to be that values of type Long and Double are not considered in the conversions done in ScriptValueTranslator.java.

For example when taking the size of a binary stream (ByteSource.size()) and pass it to a node property, it will be converted to String.
