Fixed fast flip detection for im_185 and trn_174h
Implemented fast flip for avr_120h, avs_170h, im_186, im_186ve, mt_145, mtl_180, rsn_110, sman_261, st_162, st_162h, trn_174, wof_602h and xmn_151
this finalizes fast flip support for all Stern SAM machines, (at least) for all its newest game revisions (both Pro and LE)
Fixed regressions by reducing the pre-shutdown time for Joctronic, NSM, Juegos Populares, after fixing timeslice issue related to the VGM file dump feature (which uses a fast timer)
Added support for the old SC-01 Votrax ROM version (wired only to the Mars - God of War Prototype so far)
Fixed regression/crashes for Elvis and Monopoly (introduced in 3.1)
