Impress Remote: Bluetooth on Windows

[Andrzej J. R. Hunt]

Hi everyone,

Impress Remote now supports Bluetooth on windows (currently only using 
the Microsoft Bluetooth stack) -- thanks to tml for pointing out why the 
headers I needed were breaking. (Control over wifi/network also works on 
windows -- the dialog which previously didn't work has started 
functioning, although I don't know why it previously didn't work / 
haven't made any changes to it.)

Connection-wise that means only Mac support needs looking at: assuming 
osl Sockets work as expected control over wifi/network should function, 
and assuming unix sockets with multicast also work then discovery should 
be functional too. Bluetooth will require a platform-specific 
implementation -- is this suitable as an easyhack?

(At the moment I'm working on polishing the UI of the app and making it 
consistent across android versions.)

Cheers,

Andrzej
