- If a player enters hitlag, put their follower in hitlag too
- If a follower exists and is in hitlag, don't update it in K_HandleFollower

Pre-emptively fixes a possible issue where a player who is exiting would have their realtime adjusted on respawn, affecting final results.

This corrects the issue where bots have the same time on exit as the last human player, and therefore tie with them, with disastrous consequences for GP.

- src/menu contains files for each menu's definitions.
- src/menu/transient contains menus which are reused in
many places or are separate from Main Menu entirely.

File names ending in "-1" are menus which contain
a submenu. The suffix is added so that the parent menu
sorts before all its children in directory lists.

It's also done so Tab completion doesn't stop such that
a hyphen (-) would need to be typed.

For example (this is how I auto complete file names):

"ex" <TAB> completes to "extras" because the choices are
"extras.c" or "extras-addons.c" etc. Now you need to reach
away from the home row of a keyboard to type a "-" in
order to complete any of the submenu file names.

VS

"ex" <TAB> completes to "extras-". You only need to reach
to type a "1" for one menu. There may be more than one
submenu and submenu names start with letters, which are
closer to the home row.
