[wip] Two steps font build

[hugosenari]

what:

I tricked it a little bit to make two steps instead of one.

Default behavior keeps working.

why:

Actual version is the best to build icon font with all icon-set, but my case has only small sub set of icons.

@font-face {
  src: url('/node_modules/third-party/library/*/*.svg');
  font-family: 'onlyMyIcons';
  font-weight: normal;
  font-style: normal;
}

plugins: [
  webfont.onlyCss({ }), // it makes icon css from your base css

  ...otherPostcssPlugins, // change your css here (ie: with purgeCSS)

  webfont.onlyFont({ fontName: 'onlyMyIcons' }) // it makes fonts only for icons left
]

Outputs (in my case) two icons selectors and font with only this two icons.

todo:

• test it a lot;
• update docs.
