Also re-optimized older icons using ImagOptim 1.5.1.

Part of #57.
Add icons for Android and iOS 7

Switch to a borderless icon for Chrome apps

Turns out Chrome doesn’t stick to the 128x128 icon when provided, so
need to make them all consistent. And since iOS and Android icons get
automatically rounded corners it’s best to use the borderless version.

Version w/ border still used for the favicon.
Stop manually copying manifest.mobile.json

Now kept next to manifest.json so the version number can be incremented
atomically (hopefully).
Set iOS version number to always have a ".1.1" suffix

Sounds more stable. =)
Create basic splash screens for iOS

Closes #57
Optimize splash screens
Add a build rule to keep version numbers in sync

Closes #59
