changed numeric precision when printing variables to 3 from 8
removed log/logln; changed print to write to logfile instead of directly to serial stream (where it can mess with api communications)
added secondary more standardized way of outputting newline escaped string
outputting log to serial can now escape newlines
added methods for retriving current logfile via json api
