New Plug-in: Windows 10 Media Controls

Hello there!

This is my very first post in this forum and also my first attempt at writing a Winamp plug-in.

Recently, I switched to Bluetooth headphones but, to my dismay, I wasn't able to use them to control Winamp. I tried several existing plug-ins, none which worked for me. Therefore, I decided to do my own research.

Windows 10 introduced a new API called System Media Transport Control (SMTC). This allows the application to announce what it's playing and also to receive the control commands. I've written a simple plug-in that employs this API:

As a result:
* Windows can display the played track, artist and cover art on the system OSD bar.
* This gives more robust handling of media keys, because Windows tries to use this API to control the playing application before resorting to legacy WM_APPCOMMAND messages.
* Out-of-the-box support for Bluetooth AVRCP. Connected BT devices can be used to control the playback. Theoretically, this should work also in the opposite direction: Capable BT speakers should be able to display the information about the played track. Unfortunately, I wasn't able to test this.

Please let me know if you have some issues or suggestions.
