- Created audio device manager which manages weak ref handles to audio devices
- Audio device handles are created with WorldContexts and accessed through UWorld objects
- All access to audio devices are now through audio device handles
- There is a main/default audio device for GEngine for use with the Editor and single worldcontext games

- Refactored sequencer to take in an object binding manager to manage the handles to objects that are being used at runtime.
- Wrote binding manager for UMG
- Added basic UFunction calling instead of setting properties directly

Followed pattern set out by texture streaming so that each chunk of audio data resides in its own bulkdata struct. It is currently possible to split audio into chunks when SoundWaves are marked for streaming but there is no way of doing this exposed at present.
Changed the parameters of FAudioDevice::GetRuntimeFormat so that the relevant SoundWave must be passed in, to allow for different formats for individual sounds/streaming options.
USoundWave::FreeResources no longer resets the NumChannels as it is unnecessary and causes sounds to be unable to play after the OGG data is flushed when attempting to switch to OPUS.

#summary Rename Trunc, Round, Floor, Ceil to TruncToInt, RoundToInt, FloorToInt, CeilToInt. Added *ToFloat versions. Repeated for FGenericPlatformMath and all derived classes for all platforms wherever applicable. Corrected comment in Fractional and added Frac() which does HLSL-style fractional (x - floor(x)). Checked for compilation on all projects (with cooking levels wherever applicable). Didn't change Fractional to Frac, this will be done in second commit.

Added an audio format for Opus, which also required a resampler to make sure that all imported sounds are converted to a compatible sample rate.
Added the speex resampler from the opus tools package to the third party source, including built libraries for windows and mac.
Changed FVorbisAudioInfo so that it inherits from an interface for any kind of compressed audio, which can be used everywhere instead of being wrapped in #WITH_VORBIS.
Added FOpusAudioInfo to decompress Opus data, not sure at this point whether it's only going to be used for streaming audio but works for non-streamed playback.
