Fix audio device log dump and move it to audio.cc rather than main.cc. std::clog needs to be flushed after each message.
Big fs.cc cleanup.
Use fs::path rather than std::string everywhere.
Logger was complaining about invalid log prefix. This seems to fix it.
Move fs:: and readFile from util.hh to fs.hh.
Rename execname.hpp to execname.hh.
Use fs::fstreams instead of stdlib (for fs::path support). Clean up includes.
