+- Added support for LIRC remote control (thanks to Carsten Koch!).
+  There are now three different remote control modes: KBD (PC-Keyboard), RCU
+  and LIRC. See the INSTALL file for information on how to enable either of
+  these modes. The default mode is now KBD, not RCU as before (to make it
+  work immediately even if there is no actual remote control).
