Espruino 2v05

Tweaks

• nRF52: If a central is connected to Espruino but isn't reading from UART, don't block waiting to send data
  
• Allow heatshrink compress/decompress to work even if flat buffers can't be allocated
  
• Lower thresholds for XON/XOFF to give more headroom with devices that are slow to respond
  
• nRF5x: Ensure gatt.connect silently succeeds if we're already connected to the device
  
• Improve free list ordering when Flat Strings are freed
  
• Added ability to compile Espruino to JavaScript with Emscripten
  
• JSON.stringify now escapes using the less efficient JSON subset of escape characters (fix #1737)
  
• Add append optimisation for string '+', and don't append to flat/native/etc strings (fix #1746)
  
• ESP8266_4MB: add optional build flag FLASH_1MB for ESP8255 & ESP01s with 1MB flash
  
• ESP8266: add optional build flag NO_FOTA to remove flash over the air functionality
  
• Increase 'Storage' library's max filename size to 24 bytes (from 8)
  
  

Removals

• Pixl.js remove SHA512 to make room for new NFC functionality
  
• Pixl.js: Removed AES functionality - unfortunately we're running low on space for it
  
• Original Espruino Board: Removed Vector font and don't add rotated drawImage to save flash
  
• Espruino Original: Removed Debugger, Tab complete, AT command networking from WIZnet networking build to free enough Flash
  
• Espruino Pico: Added a normal build that doesn't contain CC3000 or WIZnet support
  
• Espruino Pico: Removed Debugger and Vector font from WIZnet/CC3000 networking versions to free enough Flash
  
• HYSTM32_28: Removed from build due to lack of interest and difficulty with increased firmware size
  
• MDBT42Q: Remove AES encryption libs by default to free up more flash memory
  
• Microbit: Add SAVE_ON_FLASH_EXTREME flag to ensure builds keep working
