[HL25] Add HD Support for titles.txt

[HaajPaaj]

Problems can emerge with positioning text depending on aspect ratio.

The example provided is the mod Poke646: Anniversary Edition, with a fan-made 25th anniversary patch to add some more features to the mod.

Immediately, I noticed that when playing this mod at 4:3 resolution, the text was positioned wrong in the game's terminal system. So, i changed the horizontal offset of the text to better suit this aspect ratio. This led to the same problem happening at widescreen resolutions, which is demonstrated in the screenshots below.

Normal (1024x768):

Widescreen (1920x1080):

It would seem to me that adding a separate "hd" titles.txt file, similar to the HD background support in the 25th Anniversary Update would make such titles easier to implement.
