Change a bit of plugins' definition (mainly generify and remove unneeded methods) && Add HeadsetEventPlugin && Code clean up

• Add DataFactory (and subclasses) to be used as a wrapper of StorageData (and subclasses)
• Generify PluginDef, PluginViewFragment, DataFactory (and subclasses) to use their related StorageData as the type parameter (so that there is no need to do lots of manual type casting and checking)
  • Fix classes using them to satisfy generics
• Add HeadsetEventPlugin to listen to headset plug in and plug out
• Remove redundant wrapper (OperationLoader.load())
• Add ValidData annotation to describe that the data is "valid"
