Make the volume overlay more functional 1/2

This Patch is to add new Volume Overlay Styles

 * Make the Icon on left touchable to go to Sound Menu
 * Always show the Phone Ring volume in expanded (for devices that have phone)
 * Always show the Alarm volume in expanded mode
 * Put an Option in Sound menu to choose a Style (see 2/2 patch)
    - Single : as default
    - Expandable : Enable the more link to expand all choosen volumes
    - Expanded : Show all volumes
    - Off : show no overlay
 * Fix a BUG that when you linked the volumes you got 2 phone icons
 * Fix a BUG when linked all volumes did not move when using hard buttons
 * Fix a BUG when you drag when linked, other expanded did not move
 * Added a default mode so non-telephone devices get Expandable by default

Note : When you are using BT in phone call
or the phone normally there is an extra expanded volume
