clients: remove FLAG_SAMSUNG_DCM10 capability

I'm not entirely sure what this flag enables.  But there are reports
that is breaks browsing on Samsung Series F TV's.  So we'll have to
disable for now, until that gets sorted out by people who actually
have Samsung TV's.
clients: add NetFront Living Connect support

Add subtitle support for NetFront™ Living Connect middleware-based
clients.  These appear to include devices from Panasonic, Philips,
Vizio, Sony, and probably more.
Wrap up version 1.1.3.
