effect math sppedup - up to 3x faster

Browse Source 
-> distortion waves 3x speedup
-> hiphotic 2x speedup
-> waving cell 1.5x speedup

* replace sin8_t by lookup-table with pre-computed values
* moved integer sin and cos to fcn_declare.h (inlined by the compiler)
* moved gamma32 to fcn_declare.h (inlined by the compiler)
* a few other small tweaks
