SYSLOG - Multicog debug/log to SD/Serial

Provides a logging/debugging system that can store information from multiple cogs (running SPIN) into one file on a SD card, may optionally echo that information to a serial terminal.

• Echo to serial port may be turned on/off at run-time.
• Each cog may have it's own description in the log file for easily finding any given routine's output.
• Can monitor variables and log their changes (like a "poor man's Viewport"), however as it runs under SPIN it will NOT capture all changes if they occur at high speed.
