Add One-Click install of JW Player to backend web setup.

LongTail Video has given consent for MythTV to provide a One-Click
install button for users to install JW Player.  JW Player's
adaptiveProvider.swf provides HTTP Live Streaming support in
flash-capable browsers.

'3rd Party Software' -> 'JW Player' on the web setup menu.

The 'Install JW Player' button will download and install a .zip
package containing JW Player and the adaptiveProvider.swf.
The .zip contents are installed under ~/.mythtv/3rdParty/JW_Player/

LongTail Video has also given permission for MythTV to redistribute
the player, so the .zip is downloaded from MythTV directly, not
from LongTail Video.
