Adopt to new OpenWrt design

[Paul Spooren]

Hi, I really like this implementation! Could you please consider create a version following the design of the current firmware-wizard here? https://firmware-selector.staging.openwrt.org/. All required icons and style information are available here https://github.com/aparcar/openwrt-branding

We could consider this version as a replacement of YAFS, depending on @mwarning s opinion

[Moritz Warning]

Sure, no objections.

Hi @aparcar, sure will apply the style guidelines.
Currently working on package selection for asu.

Great, let me know if you need anything from me.
