Version 2.1.6

Change Log:

• Added a Buzzer chip for creating sounds.
  • This has a 4-bit volume input, and an 8-bit frequency input. The frequency range is from 27.5 to 3729.3 Hz.
    
  • It can be found in the 'Other' collection in the chip library
• Slightly relaxed bounding box checks during chip placement, allowing chips to be packed more closely together if desired
• Fixed bug where cancelling placement of a chip while over another chip would cause it to be placed there. (Thanks to Squiggles on GitHub)
• Fixed bug where wires would get messed up if moving a group of chips immediately after duplicating them
• Fixed bug where bus-lines and output pins could have incorrect colours when receiving multiple tri-stated inputs
• Fixed bug in the ‘jump’ up/down behaviour in the chip library
