1) DT plugin for Firefox does not have mime info under MozillaPlugins.
   JavaPlugin has it. We should be consistent

2) JavaPlugin info is not complete for 8 as 1.8 entry is missing.
   Code need to be conditional and add 1.8 entry if build for JDK8

3) We need to add
    application/x-java-applet;deploy=10.0.0
   type where version string is version of deploy stack.
   It is important to be able detect version of java plugin without loading DT libs.
   (one less security popup in chrome)

4) We also need mimetype for true javafx cobundle.
   There is no "true" cobundle on Windows yet but would be good to add codechange that will
    be in effect once true cobundle will be produced by install team.
