Moved all compile targets to package.json and add preinstall

An alternative to #120 - also adding the `preinstall` target from https://github.com/AsaAyers/coffeelint/commit/53330e6f52bc992dfc264c126448ecd45ea0123f to allow installing directly from a git URL.

Just thought I'd put it out there - can understand if you'd prefer to have a separate build file for readability - this just makes things easier from an end-user perspective.
