Share icon packs between desktop and Android

Browse Source 
The Android app's Material icons become a TeamSpeak-format pack shipped in
core, which the desktop offers next to the TeamSpeak packs. Android now
draws its icons from packs too and imports TeamSpeak's own zips, falling
back to the Material pack for what they lack.
