[mythtv] Patch: Mythmusic pageup/down in playback

[henri]

added callbacks for pageUp and pageDown in the playbackbox

Issues:

- my keybindings are very different than the stock ones, so
i didn't know what to put in the defaults in main.cpp
(pageUp / pageDown makes sense to me, but they are bound to
something else already)

- not sure if it's possible to change this, but when i page
up or down it centers the current selection, rather than at
the top or the bottom of the visible items (like in the
playlist selection windows)
