quakespasm: Update to 0.93.2

Changes in 0.93.2:

  o Lightmaps are now dynamically allocated (from QSS), and
    BLOCK_WIDTH/HEIGHT raised from 128 to 256.

  o Fixed several uncheked limits that would crash the Slayer's
    Testaments mod (sf.net bug #33).

  o Raised MAXALIASTRIS from 2048 to 4096, so that the Slayer's
    Testaments mod works.

  o Fixed 'pants' and 'shirt' types so that those textures load
    correctly on platforms where char is unsigned by default
    (sf.net bug #28).

  o Windows audio: WASAPI-enabled SDL2 dlls function properly now.

  o Update the third-party libraries. Other fixes/cleanups.
