v3.0.0

It is a complete rewrite of the code in TypeScript to clean up and start on a good basis.

New

• The directory where gulpconfig.yml is the current working directory where
  you could put configuration files like .babelrc, .browserslistrc,
  .eslintrc...
• Discreetly introduce in previous version, svgstore is officially in this
  version. You could combine SVG files in One.
• Browserify is now manage by it's own tasks.
• New webpack tasks to package javascript files.
• New clean task to delete directories and files before other tasks run.
• Experimental revision that build a JSON file with all generated files
  and some hashes (MD5, SHA1 and SHA256) sort by tasks. This could be used in URL
  parameters as cache buster.
• Build tasks now exit on error with an error code equal to 1, that mean you
  can use it in CI/CD process.

Breaking changes

• javascript tasks no longer use browserify. It's only a concatenation
  task with Babel.
• In sass tasks, default sort for media queries is "mobile" instead of desktop.
• Remove name settings on fonts tasks.
• Data for pug tasks is no longer merged between global and task settings.
