All versions of Home Network SSL Checker

[1.5] KitKat compatibility: Require additional permission to read a certificate file from USB storage. Now uses file manager to find certificates if none found internally. Added high-resolution images. [1.4] Configuration option to not display a notification for "single-red". Note: on reboot, under some circumstances, the widget won't start. That's a documented Android restriction. Tap on the widget and "Check now" when it remains grey.
