Added in the ability to write logs to a log file as well. For now the
logs write to ./quantum.log. All new log entries append onto the end of
the log. Also added timestamps in front of all log entries that are
generated when the log entry is made.
Got a very basic logger up and working. Can be used with the Q[LEVEL]
macros. Still needs some work to add coloring to the console and to be
able to write logs out to files.
