Release 1.8.13

IDE

• Fixed crash on MacOSX >=10.15 with multiple monitor setups.
• The boards in the boards list in the "Tools" menu are now grouped by platform. This should make the selection
  easier when there are lots of boards loaded in the IDE. (thanks @matthijskooijman)
• Fixed save of proxy username/password settings in "manual proxy" section.
• In "Tools / Programmers" menu only shows programmers related to the currently selected board. (thanks @matthijskooijman)
• Fixed: sketch window out-of-display if the IDE is restarted after removing an external monitor.
• Allow baudrate/config change when the Serial Monitor/Plotter is disabled. (thanks @matthijskooijman)
• Updated jmdns to 3.5.5. Should improve network board detection.
• Optimized libraries scanning during startup. (thanks @ricardojlrufino)
• Better vertical centering of file names in tabs. (thanks @ricardojlrufino)
• Better console rendering of progress bar during upload. (thanks @matthijskooijman)
• Fixed invalid http "Accept" header.

• FIX REGRESSION: Fixed precompiled libraries containing "wrapper" code that has to be compiled together
  with the precompiled part.
• Removed automatic '--relax' for compiles on Atmega2560 MCU
• Fixed skethbook+bootloader hex merger when the bootloader is in .bin format.
• Fixed relative path errors when traversing different partitions (in particular on macosx for larger sketches)
