* Doom, Doom 2, Heretic: customizable ammo capacity
* Do not progression balance capacity up items
* Prog fill still doesn't agree, just go with our original idea
* Clean up the new options a bit
- Gave all options a consistent and easily readable naming scheme
(`max_ammo_<type>` and `added_ammo_<type>`)
- Don't show the new options in the spoiler log,
as they do not affect logic
- Fix the Doom games' Split Backpack option accidentally referring to
Heretic's Bag of Holding
The logging change across all three games is incidental, as at some
point I did run into that condition by happenstance and it turns out
that it throws an exception due to bad formatting if it's reached
* Do the visibility change for Heretic as well
* Update required client version
* Remove spoiler log restriction on options
* Remove Visibility import now made redundant
for doom 2, some of the armor and health weights were nudged down
to compensate for the addition of the megasphere
for heretic, the torch was just added without changing anything else,
as I felt doing so would negatively impact the distribution of
artifacts (and personally I already feel there's too few in a game)
