3.2.7 fixes; tweaks of j2sApplet.js and j2sClazz.js - #140

fixes isssue with annotations with fields that are annotation arrays
with non-null defaults. For example,

public @interface Menu {}
public @interface Plugin {
	Menu[] menu() default {};
}

added options for Wei to experiment with direct JavaScript use of
Clazz.new_, swingjs.JSUtil.getFileAsBytes$O(name), and
J2S.getFileFromDialog(fDone,format)
