Patch to add better feedback on LCD during DVD playback

[maillists@…]

Patch to improve information displayed on LCD when playing a DVD.

Does the following:

• Improves retrieval of DVD name by using a different location (from that of the included libdvdnav) if the name is encoded the 16bit notation. Alternative location gleemed from lsdvd source. If no displayable name can be found uses a default of "DVD". Strips trailing spaces and replaces underscores with spaces.

• If in a menu (as detected by IsInMenu?()) displays DVD Name and indication of being in a menu.

• Otherwise displays DVD Name, Title number and its length, Chapter number and the number of chapters in the title.

• Doesn't display the progress bar when in a Menu - was previously stuck at 100% complete.

Leverages the switchToChannel and associated functionality to do this (ie. lcdCallSign, lcdTitle and lcdSubtitle)

Not sure if I've done the right thing with the tr() calls.
