1000 bugs which may have been fixed

[guy-59]

hi. i decided to play through the '0.39' version as well as look inside the code, and have discovered many bugs (as well as some nitpicks)

1. periods '.' and lowercase 'b's will appear as the letter before them, then are fixed a frame later.
2. when activating menus (maybe only the g menu?) a bunch of text sounds will play at once
3. the '2' and '8' still use the Z and B assets instead of their actual sprites (can be fixed in bssp8)
   
4. reaper sans's spawner effect is never deleted, and leaves behind two thin black lines that can be seen when HO!sans is spawned
5. science sans mini-bombs do not spawn because the mtt spawner never reaches 'frame_index 10'
6. in outertale sans's attack, bl1 is set to 0 upon creation, overwriting the intended value 15. so instead of the box moving upwards, it moves downwards
   
7. 'HO! sans' attacks do not hurt you after getting hit once, because there is no 'a' decrease in the cold_hot code
8. regarding the fourth attack of phase 2 'stay in the box' (but_18), in older versions (0.22, 0.25) the flames near the end of the attack would allow you to dodge them in the middle of the box.
   
   later versions possibly had value 'b' not reset properly, so you are forced to be at the very top to dodge properly
9. some attacks are horribly balanced compared to others, such as 'OnlyFunny' sans in attack 5 of phase 2, and some of the phase 3-ex attacks
10. i think the overheal that can be given by the first 'G' pie is intentional. it previously would write itself into the save file
11. i need undysans back
