B2S Server v2.1.1

• Add B2STools/B2SRandom.cmd to randomize many Backglasses when activated in Pinup Popper or similar
• Backglasses using overlapping partly transparent pictures get it's events merged. This is now deactivated by default.
  Can be activated in the direct2BS file (there is NO GUI):
• Add support for PWM modified tables, the light turn on values > 64, if it is a PWM activated table:
  There is a new setting for VPinMame.SolMask(2) to set the output mode:
  0 = default
  1 = modulated (PWM) solenoid (exist for some years already)
  2 = new PWM mode (all solenoids but also lamps and GI-lamps, and value if physic meaning, not smoothed out binary state)
  For this new mode, we now hardcode a value 64, if the lamp intensity exceed this value, it is binary 1
• b2s_screenresidentifier: Add Comments hidded behind the taskbar #77
• "Fantasy" setting in B2STableSettings.xml is ignored #93
• re-registering B2S.Server should first cleanup earlier entries #98
