Features

Music and sound stuff galore!
- Enhanced music using MP3 and OGG can now be given loop points and crossfade timings in the DMap editor. The music will then loop at those points and fade in and out with those timings.
- Scripts have new ways to interact with enhanced music: GetMusicPos(), SetMusicPos(), SetMusicSpeed(), GetMusicLength(), and SetMusicLoop()
- Scripts can also play music with crossfades using CrossfadeEnhancedMusic().
- Scripts can play sounds with different, volume, pan, frequency, and looping with PlaySoundEx().
```
// Turns a SFX into an instrument by playing it back at different frequencies
ffc script Piano
{
   void run()
   {
       // Frequency values and keys for different notes
       int hz[] =   {16350L, 17320L, 18350L, 19450L, 20600L, 21830L, 23120L, 24500L, 25960L, 27500L, 29140L, 30870L, 32700L};
       int keys[] = {KEY_Z,  KEY_S,  KEY_X,  KEY_D,  KEY_C,  KEY_V,  KEY_G,  KEY_B,  KEY_H,  KEY_N,  KEY_J,  KEY_M,  KEY_COMMA};
       int sz = SizeOfArray(hz);
       int sfx = Rand(60); // Pick a random SFX
       while(true)
       {
           for(int i=0; i<sz; ++i)
           {
               if(Input->KeyPress[keys[i]])
               {
                   int j = (hz[i]/hz[0]) * 22050L; // Multiply by the sample rate of most default SFX
                   Audio->PlaySoundEx(sfx, 100, 0, j);
               }
           }

           Waitframe();
       }
   }
}
```
- Scripts can also adjust sounds mid playback with AdjustSound() and track their completion with GetSoundCompletion().
```
ffc script AdjustSound
{
   void run()
   {
       // Play the sound panned to the left at half volume
       Audio->PlaySoundEx(SFX_SECRET, 50, -128, -1, false);
       // Run until the sound has stopped playing
       while(Audio->GetSoundCompletion(SFX_SECRET)!=-1)
       {
           int pct = Audio->GetSoundCompletion(SFX_SECRET) / 100;
           // Pan the sound to the right while increasing in volume
           Audio->AdjustSound(SFX_SECRET, Lerp(50, 100, pct), Lerp(-128, 127, pct), -1, false);
           Waitframe();
       }
   }
}
```
- Scripts can set MusicRefresh to prevent music from resetting when changing screens
```
Audio->PlayEnhancedMusic("ExampleSong.ogg", 0);
Audio->MusicRefresh = MR_DMAP; // Music will refresh on changing DMap
Audio->MusicRefreshFlags[MRF_REVERT] = true; // Music refresh with revert to default behavior afterwards
```
- AdjustMusicVolume() and AdjustSFXVolume() have been reworked to be a multiplier capped at the user's volume settings, rather than overwriting those settings.
