Additional Lircmap.xml entries for MCE remote

[simonowen]

My MCE remote is detected as a "linux-input-layer" device, and has some keys not handled by the existing entries. The new ones needed in Lircmap.xml are:

            <aspectratio>KEY_ZOOM</aspectratio>
            <mymusic>KEY_RADIO</mymusic>
            <mypictures>KEY_CAMERA</mypictures>
            <mytv>KEY_TUNER</mytv>
            <menu>KEY_MEDIA</menu>
            <clear>KEY_DELETE</clear>

I needed a few extra entries for 1.0a4, but it looks like they're already merged in ready for beta 1, so I've not included them here.

Done, thanks!
