Half-Life Splash Texts

Adds 124 Half-Life related splash texts!

These are mostly in-game dialogue, as well as a handful of references to the community.
This is entirely based on Half-Life 1.
All texts have a similar style to the quirky messages in vanilla.

A complete list can be found here.





Side note: I don't know much about the Half-Life series, so the references may be limited. I just like the silly scientist dialogue.
