- The information stored in `makeImage`'s `options` parameter is better served in its `data` parameter, - Remove the (no longer used) `colorscheme` parameter to `makeTemplate`, - We can already get to the contents of the URL query parameter `style` through that `data` parameter in `getRequest`, - Relocation of the code to set badge data related to the flat style into `getBadgeData`, - Code style (adding semicolons). Related to issue #159.
