STOP breaking backwards-compatibility with patch versions

[paulmillr]

Seriously, folks.

1.0.10 compiles stuff in one way and 1.0.12 compiles it in totally different way.

Please stop breaking compat with patch versions. Breaking it with 1.0 -> 1.1 is totally fine.

lots of users depend on proper semantic versioning. gh-547, brunch/brunch-with-chaplin#75, http://ost.io/@brunch/brunch/topics/89 etc

We had semver issues that forced us to do patch versions. The next version will be 1.1.0-alpha.01. We have had discussions and the goal is to not break the runtime and precompiler API until we hit 2.0, whatever that may look like.

That being said I strongly suggest running your runtime and precompiler in lock step as this is what is tested by our test suite, not permutations of versions.
