Need to implement device specific locaton capture about a2dpvolume HOT 4 CLOSED

I think I will use the long press event for the device in the lost to retrieve 
the last location of that device.  I will leave the current location button in 
tact to show the location of the last disconnected device.  This should just 
require adding either columns to the current table, or a new locations table.  
I think I prefer the latter (adding a new locations table).  A new table would 
give us more flexibility and potentially allow us to store more than one 
location per device.  Maybe we keep the last xx locations.  Maybe we keep them 
all but add a utility to clean up the old ones periodically.  Open to 
suggestions on this.

Adding this feature would drive more complexity and a fair amount of work.  It 
will also take more space on the device.  Now I am wondering what the use cases 
are.  Do we even need this?  

A simpler option would be to add columns to the devices data table.  Then store 
only he last location there.  This would more than double the table size but it 
would still be small.

I added this to 1.3.9.  It now creates a file for each vehicle in the data 
export directory.  This file is an html file that will show a link with the 
vehicle name when opened in a browser.  Clicking the link will launch the 
location just like the widget does.

Fixed in version 1.4.0.

When a location is captured, an additional data file is now created in the 
BluetoothVol directory on the SD card.  This is an html file with a link to the 
location data that can open in any app that reads location data.  In addition, 
the file also has more data about the location displayed for the user.

Long press of a device in the list will open a dialog showing details about 
that device.  There is also a location button in this dialog now.  Clicking 
this button will open the last location data file for that specific device.
