Do turn the icons blue

For the last one, #594, i didn’t actually update the icons, because i thought that there might be some special code that could or should be added to the commit.

Then i went and accidentally installed a version without the icons. Bad idea. Presumably because of the widget, which i use, that messed up my whole system. I couldn't get past the unlock screen.

I finally had to install an apk with the icons through the recovery system.

To make sure that that doesn't happen again, here the icons.
