In particular, the keymap for the Nova-T (sub 13c2:1011) is switched to the Hauppauge grey/black keymap, of which the keys on the supplied R808 remote control form a subset. The old budget-ci keymap is moved to ir-keymaps.c and is used for other remotes. The debounce logic for buggy remotes (i.e. Zenith) is made conditional the new debounce parameter and defaults to off (so that repeat keypresses aren't ignored for all working remotes). Some parts are based on Darren Salt's dvb-ir patchset.
