Update to v098r05 release.

Changelog:
- WS/WSC: re-added support for screen rotation (code is inside WS core)
- ruby: changed sample(uint16_t left, uint16_t right) to sample(int16_t
  left, int16_t right);
  - requires casting to uint prior to shifting in each driver, but
    I felt it was misleading to use uint16_t just to avoid that
- ruby: WASAPI is now built in by default; has wareya's improvements,
  and now supports latency adjust
- tomoko: audio settings panel has new "Exclusive Mode" checkbox for
  WASAPI driver only
  - note: although the setting *does* take effect in real-time, I'd
    suggest restarting the emulator after changing it
- tomoko: audio latency can now be set to 0ms (which in reality means
  "the minimum supported by the driver")
- all: increased cothread size from 512KiB to 2MiB to see if it fixes
  bullshit AMD driver crashes
  - this appears to cause a slight speed penalty due to cache locality
    going down between threads, though
