updates for 1.1, 1.2, 1.3 and 2.0

I'll be releasing `2.0` at some point in the next day or two.  Making a pass through all the examples and skeletons to do a quick update to them.

The tracking file is part of some caching that the require module does as of a few months back.

The rest are updates specific to `2.0` and the breaking out of compilers from mimosa core.
