HF Button Widget (<=KitKat)

**To start, add the widget to your home or lock screen.**
When headphone is inserted, this widget can toggle your headset audio off, to have the sound come out of your built-in speaker or even connected bluetooth.
An indicator dot tells you if sound is going to come through the headphones when there's media sound playing.

Branch of https://code.google.com/p/toggleheadset2/ for personal use, with bug fixes...
Removed call detection features and on-boot settings. Supports both headphones and headsets. Playing music to bluetooth when headphone/headset plugged in is now possible.
This app just tells Android to pretend as if the headphone is not plugged in even though it is.

If headphone/headset is plugged in with bluetooth A2DP attachment, the volume control might be either bluetooth media or the ordinary media audiostream. That's Android getting confused about where the music is actually being played, because this app pulls the rug from underneath it.
If you have a HTC device with a self-toggling headphone jack, the widget will be updating itself too much.
The way this app works results in conditional unpredictable behavior, particularly with phone calls. Hence, this app is alpha and will stay that way.
Should probably merge this into another app someday, but for now it's useful for various things...

A review indicates that this allows the use of the integrated speakers with 1seg (ワンセグ) on the KDDI HTC J One.
