(MESS) nes.c: improvements and fixes to inputs [Fabio Priuli]

Browse Source 
* simplified input reading
* moved most Famicom controllers to the expansion port
(still configurable in the Driver Config menu) because it is
more accurate and because it allows to use both the FC
keyboard and the controllers in BASIC games
* fixed NES paddle emulation which broke some years ago
* added FC paddle emulation, see Arkanoid and Chase HQ
* added Hori Twin Adapter with correct P3 & P4 Famicom 
protocol, see e.g. four players games by Technos Japan


just a cleanup and the whatsnew entry for previous changes...
