* Reduce code size by removing nullptr assignments * Optimize tagDB for loops * More tagDB optimizations * Remove static from language arrays reducing RAM by 5128b - Reduces Flash by 13060b * Add missing extern in tag_db.h * Fix deprecation warning of sntp.h * Remove static from contentmanager, reduces RAM by 184b * Use string reference in prepareDataAvail - Remove some unneeded buffers - Remove some gotos
