Extracted code from computeClassPath() that finds the innermost class loader to a method so that it can be overridden (for languages that derive from Java and use additional ClassLoaderImpls). Added some type parms. computeClassPath() now skips FileModules, in case any "leak" into the module set. Added overridable method skipSourceFile() so that generated source that's in the source path can be skipped (e.g. Java source generated from X10 source files).
