Contributed several fixes to the first 3 tutorials. The first 2 seem good so far, but the 3rd seems to include code I can't replicate or find to exist. Will have to come back around to figure out what's up with that.

Edit: I misread and misinterpreted the inspector code at the end of the tutorial. This is my fault. The third tutorial works and looks good.

Made some progress over triple checking the last tutorials. Tutorials 4 and 5 should be in good order now, at least from a code perspective.
