Typo and formatting fixes in include/audiality2.h.cmake
Updated debug function a2c_T2S() to current token set
Added 'setall' instruction

Added VM instruction SETALL with A2S keyword 'setall'. The instruction
forces all control registers that are marked for ramping to instantly
jump to their target values, with no ramping, as if 'set' had been used
on each one of them.

Closes #165.
