36e636dca1 Drop support for versions of Node prior to v4.
Reduce production (sub)depedency count from 93 to 50.
Modernise dev tooling, e.g. use nyc, replace jshint with semistandard.
Make 'npm test' command consistent across platforms.

3f5e38bb62 Deprecate output format option functions.
Access is now via options of existing output format functions.

e.g. use .jpeg({quality: n}) instead of .jpeg().quality(n)

e6bfa52b0b Add raw pixel data support to boolean and withOverlay ops
The previously-scattered image opening logic has been refactored to a
single ImageDescriptor struct/Object available to both JS and C++ code

This removed about 150 LOC but more importantly reduces the complexity
of adding/exposing new operations that require an input image.
