This change fixes minor bugs and adds a feature, which lets us store the ELF symbol table, inside the ZIP directory. We use the path /zip/.symtab which can be safely removed using a zip editing tool, to make the binary smaller after compilation. This supplements the existing method of using a separate .com.dbg file, which is still supported. The intent is people don't always know that it's a good idea to download the debug file. It's not great having someone's first experience be a crash report, that only has numbers rather than symbols. This will help fix that!
