Feature/302 add diff output options (#345)

• refs #302 refactor makeconfig
• refs #302 renames customBackstop to projectPath
• refs #302 refactor makeConfig
• refs #302 adds resembleOutputSettings

extracts extendConfig to make it testable

Include BackstopJS in node scripts

const backstop = require('backstopjs');

backstop('reference');

// handle the response like this
backstop('test')
  .then(() => {
    // test successful
  }).catch() => {
    // test failed
  });

// pass options to the command
backstop('test', {config:'custom/backstop/config.json'});

Since the backstop runner returns promises it can easily be integrated in build systems like gulp

const gulp = require('gulp');
const backstopjs = require('backstopjs');

gulp.task('backstop_reference', () => backstopjs('reference'));
gulp.task('backstop_test', () => backstopjs('test'));

Special thanks to @nobso for this great feature!

BackstopJS 2.0 -- The rewrite!

Massive performance gains and many new features. Many thanks to @JulienPradet, @onigoetz, @borys-rudenko, @Ksushik, @dmitriyilchgmailcom, @Primajin

Highlights

• Completely removed gulp, rely only on fs to move files around
• Added a modal to show the images in big, with a slider to compare images in place.
• The report doesn't need a server to be seen
• To see the report, the files are copied in the project (previously the images were copied into Backstop)
• Backstop relies on process.cwd() to generate its path, not ./node_modules/backstopjs
• Add a --filter option to filter scenarii by label in test and reference

  Variants

• You can add "variants" to a scenario, they have the same options as a scenario, but are checked against the main scenario
• no reference is created

  Browser reporting

• Removed resemblejs, use images generated by the CLI reporter. (we have more than 500 tests, running them in the browser just breaks the browser)
• Copy the reporter files to the project.
• The reporter required to disable the CSP rules of our Jenkins server, not longer the case
• Added a way to toggle the summary of scenarii
• Added a modal on click on reference or test image with a comparison slider
• Tweaked the styles a bit
  • Removed custom "circles" to show the number of passed and failed tests : replaced with Bootstrap's "label" because with more than 100 tests, the circle is broken
  • Made a more compact "Report" section : removed analysisTime and dimensionDifference (if isSameDimensions is true)
  • Changed the font stack (there was a typo)

    CLI Reporting

• Reporting is always run in the CLI and results added to an object
• You can easily add multiple new report types with this new object
• junit report was moved to a separate code block to not clutter the main one

  Internal changes

• paths are made from the current working directory, not backstopjs.
• removed the need for an internal hash of the configuration.
• the list of comparisons to create is stored in a special temp file.
• commands no longer have a before and after this makes the code very complicated to understand and can be replaced by promises inside the main execute
• removed "start" and "stop" commands as the server is not needed anymore.

  Bugfixes / Regressions

• If the tests failed, the return code was still 0
• You could not use a JavaScript configuration anymore
• Errors in Promises were swallowed

  Code Style

• Replaced jshint/jscs with eslint
• Linted with "semistandard"

  Tests

• Run tests on travis on more node versions (0.12, 4, 5, 6)

Bug fixes

• findExecutable
• path fixes for Win OS
• fixes for legacy mode
