Maptext 2023 tweaks 3 (#76552)

## About The Pull Request

Hopefully the last set of changes in this demonstration of the
[Goldilocks
principle](https://en.wikipedia.org/wiki/Goldilocks_principle).

Some more font changes, the big (hah) one being the context tooltips
again.

- Context tooltips smaller main line, more compact sublines.
- Improves documentation on the usage of the macros.
- Removes incorrect comment I added earlier in tgstation.dme
- Adds black outlines as default in the macros.
- Icon sized letters (Dwarf Fortress, credits).
- Deathrattle and other actions reduced spacing.
- Aligned cooldowns/countdowns.
