0.2.21

• Removed the SQLite database - Incoming push messages are stored in a log file instead of the database, so no need for SQLite anymore (slow builds)
• Removed the image processing library - caused a lot of issues with building the image on different platforms. Thumbnails are now always downloaded a second time after 1 second, to make sure they are present even if the push arrives before the image is complete
• Added support for T8220-Z (thanks @jasonpaustin)
• Added support for T8144-Z
