[Open Assets] Ridge Racer 7 announcer v1.6

I don't feel motivated to work on this anymore. I understand that this is pretty much incomplete, but I encourage anyone with coding expertise to fix this mod themselves, please.

-New voicelines

Quote	Conditions
"Okay, get ready to race!"	Immediately on map load
"Good luck!"/"See you at the finish line!"/"Challenge the world record!"	Briefly after the countdown. The last quote is triggered when racing alone

-Lap count voicelines are bound to individual players
-Better organization for those peeking into the code, also cleaned up the code a bit
-Other stuff I prolly lost track of

Apparently the rr7_shutup command breaks sync within a server so... I do apologize for any inconveniences to those that encountered this issue.

• Adjusted the lua so it doesn't break the sync when activating rr7_shutup
• Somewhat better documentation for if you just want a peek into the code.

• With the rr7_shutup (default: Off) command, players can mute the announcer if they opt to. This is a client-side command.
  • rr7_enable (default: On) is also a thing, similar functionality except it is serverside.
• Simplified some P_RandomRange stuff as apparently I overcomplicated stuff and broke some stuff.
• "Go go go!" no longer plays when doing a drop dash. That voice clip has been repurposed into Grow/Invincible checks.

Minor fixes for consistency with the original game.

-Several new voicelines! They're as follow:

Quotes	Conditions
"Time attack is over!"	Complete a race with only yourself in it
"Congratulations on winning a 1-on-1 battle!"	Complete a race against one other racer
"FLOOOR IT!"/"Go go go!"	Use a invincibility/grow!
"1 minute remaining.", "30 seconds remaining.", "10 seconds." "5... 4... 3... 2... 1..."	Countdown timer starts. I know the default is 30, but I allowed for 60 here.
"Check"	Placeholder. Why is it here? You tell me.

-Attempt to make the announcers a bit more dynamic
-Some voicelines change

Changed the lua a bit
