InfiniTime 1.14 Update

Here is a summary of the changes and addition of InfiniTime 1.14:

• Reduced memory footprint in flash memory: the analog watch face draws the background at runtime instead of using a pre-defined background picture and we moved the font for the navigation app to the external memory.
• Improved raise-to-wake algorithm and new lower-to-sleep functionality
• New weather service and new setting to select °C/°F
• The build system now allows to easily select which user applications and watch faces are built into the firmware
• Replace the node.js tool that convert the images (lv_img_conv) by a custom re-implementation in Python
• InfiniLink, the iOS companion app has a new maintainer!
