0.4.0

• New feature: Add landfill to every tile of a blueprint that needs it.
• Removed code that disabled blueprint flipping and mirroring when a competing mod was installed.
• Support Factorio 0.17's new shortcut bar. Adds shortcuts for all operations (except nudge/snap). Shortcuts are enabled whenever a configured blueprint is in your hand.
• Add our own shortcut bar that appears while a blueprint is held to perform all operations (except nudge/snap). Factorio's shortcut bar is pretty limited in size, so this gives you an alternative. Individual buttons can be turned off in mod settings; the entire button bar is hidden if you turn off all buttons.
• Substantially overhauled internal event handling code.
• Lots of code cleanup.
