Compass bug fix

- HMC6343.c - SendCommand was not returning "true" when it was supposed
- this caused the compass readings to always "fail"
- Re-arranged how main.cpp prints out information
- Added CodeBlocks Makefile for easier building from command line
-- Debug/Release builds
-- Makes it easier to add files to the project without having to hand edit Makefile
- New files are located in the GpsBoat folder where all CodeBlocks related files are
