* Move the visitation flags, Record Attack/NiGHTS Attack data, and emblem checking to outside of Y_StartIntermission.
* Y_CleanupScreenBuffer never got called for maps which skip the intermission, leading to a small memory leak; this is now fixed by moving it to G_AfterIntermission.
* Y_FollowIntermission was just G_AfterIntermission with modeattacking specific behaviour, but this is desired for all places where G_AfterIntermission is called, so just merge this into G_AfterIntermission.
Notably, these changes are necessary because there are now three maps in the main SP campaign which do not end with traditional intermissions. As a result, this fixes an issue where Black Core's tracks are not available in the Sound Test (due to MV_BEATEN never being applied).
Also, since I was here: Remove "gotperfect" from recorddata_t. This is a duplicate of `mapvisited[gamemap-1] & MV_PERFECT` which uses more memory. I have kept the new spacing in the gamedata for compatibility with RC1 savedatas, but moved it across to the original method everywhere else.
- Move K_SetPowerLevelScrambles to G_DoCompleted
- Fix wrong gamespeed being displayed in strings
- Add defines for kartspeed values
- Disable Easy scrambles again
- Corrupt gamedata if pwrlv is in invalid range (gets corrected in-game, and doesn't really matter to anyone who knows what you're doing, but it'll stop at least the most basic script kiddie)
Replay menu will still display wrong speed name, but it's fine in the replay itself.
* Show emblem requirement on record attack menu
* Use bigger emblems on the menu.
* Display your best number of collected rings in yellow if reached perfect bonus.
* Adjusted XTRA frames (again)
- m_menu.c and m_menu.h are dead. Everything has now been moved to k_menudef.c, k_menufunc.c, k_menudraw.c, and k_menu.h.
- Expanded menu_t and menuitem_t to add transitions and tooltips
- Early character select screen
- Removed almost all menu definitions, I'll be reimporting them as they are needed
- Capsules get spawned in the proper scenarios
- Level ends when all capsules are busted
- Time gets used on the leaderboard instead of score
Also split a handful of Battle code into k_battle.c. Lots of other code could probably get moved here later
