Update FuncSigs.hs

[ChloeConstantine]

Fixed function signatures; some of the new ones had DataData in them

[KoolLSL]

A fix:
("llSetEnvironment",LLInteger,[LLVector,LLList]), instead of ("llSetEnvironment",LLVoid,[LLVector,LLList]),

Some recent functions:
("llLinkAdjustSoundVolume",LLVoid,[LLInteger, LLFloat]),
("llLinkPlaySound",LLVoid,[LLInteger, LLString, LLFloat, LLInteger]),
("llLinkSetSoundQueueing",LLVoid,[LLInteger, LLInteger]),
("llLinkSetSoundRadius",LLVoid,[LLInteger, LLFloat]),
("llLinkStopSound",LLVoid,[LLInteger]),
...
("llLinkAdjustSoundVolume",(["link","volume"],"Adjusts volume of attached sound.\n")),
("llLinkPlaySound",(["link","sound","volume","flags"],"Plays attached sound once at volume.\n")),
("llLinkSetSoundQueueing",(["link","queue"],"Set whether attached sounds wait for the current sound to finish. If queue is TRUE, queuing is enabled, if FALSE queuing is disabled. Sound queuing is disabled by default.\n")),
("llLinkSetSoundRadius",(["link","radius"],"Establishes a hard cut-off radius for audibility of scripted sounds (both attached and triggered).\n")),
("llLinkStopSound",(["link"],"Stops the attached sound(s) currently playing, if they were started by llLoopSound.\n")),
