1. Introduce include_dir for use with gyp in a scalar context …

   Deprecate use of `include` in an gyp array context, which
   happens to work when paths are absolute, but can fail on Windows
   when paths are relative and a gyp file contains multiple entries
   in its `include_dirs` directive.
   
   This change corrects documentation and tooling, adds support for
   relative paths (e.g. those containing whitespace) in a backwards
   compatible manner and makes the approach holistically consistent
   with that used by nan.
