Version 5.3 (20191004-112306)

• Fixes external USB/UVC webcam support
• Makes various bugfixes and improvements to Blocks page, including but not limited to:
  • Many visual tweaks
  • Browser zoom and window resize behave better
  • Resizing the Java preview pane works better and more consistently across browsers
  • The Java preview pane consistently gets scrollbars when needed
  • The Java preview pane is hidden by default on phones
  • Internet Explorer 11 should work
  • Large dropdown lists display properly on lower res screens
  • Disabled buttons are now visually identifiable as disabled
  • A warning is shown if a user selects a TFOD sample, but their device is not compatible
  • Warning messages in a Blocks op mode are now visible by default.
• Adds goBILDA 5201 and 5202 motors to Robot Configurator
• Adds PIDF Annotation values to AndyMark, goBILDA and TETRIX motor configurations.
  This has the effect of causing the RUN_USING_ENCODERS and RUN_TO_POSITION modes to use
  PIDF vs PID closed loop control on these motors. This should provide more responsive, yet stable, speed control.
  PIDF adds Feedforward control to the basic PID control loop.
  Feedforward is useful when controlling a motor's speed because it "anticipates" how much the control voltage
  must change to achieve a new speed set-point, rather than requiring the integrated error to change sufficiently.
  The PIDF values were chosen to provide responsive, yet stable, speed control on a lightly loaded motor.
  The more heavily a motor is loaded (drag or friction), the more noticable the PIDF improvement will be.
