LADX: tweak in-game hints

[threeandthreee]

What is this fixing or adding?

Just sticking to what's been asked for this time :)

All in-game hints are for the local player's items, so this removes the player name from the hint text to save some space. https://discord.com/channels/731205301247803413/1205697512237830225/1205699695851077702

Also adds an option to disable in-game hints entirely, which would allow LADX to be used in no-hint games.

How was this tested?

Generated games, checked hints.

If this makes graphical changes, please attach screenshots.
