Add possibility to choose between local CSS folder prefix and remote url

[yukoff]

Hi,

Sometimes it is useful to use remote url instead of downloading fonts locally, so with the option set to use remote url CSS snippet would be generated to something like

/* merriweather-300 - cyrillic-ext */
@font-face {
  font-family: 'Merriweather';
  font-style: normal;
  font-weight: 300;
  src: url('//fonts.gstatic.com/s/merriweather/v13/ZvcMqxEwPfh2qDWBPxn6nrR_0bxNg2oCMKP8--GWw48.eot'); /* IE9 Compat Modes */
  src: local('Merriweather Light'), local('Merriweather-Light'),
       url('//fonts.gstatic.com/s/merriweather/v13/ZvcMqxEwPfh2qDWBPxn6nrR_0bxNg2oCMKP8--GWw48.eot?#iefix') format('embedded-opentype'), /* IE6-IE8 */
       url('//fonts.gstatic.com/s/merriweather/v13/ZvcMqxEwPfh2qDWBPxn6ni-KWXw7CoiyPmiAwGgQ-pk.woff2') format('woff2'), /* Super Modern Browsers */
       url('//fonts.gstatic.com/s/merriweather/v13/ZvcMqxEwPfh2qDWBPxn6ngNLn4qwG1odAuDXh3L2pVg.woff') format('woff'), /* Modern Browsers */
       url('//fonts.gstatic.com/s/merriweather/v13/ZvcMqxEwPfh2qDWBPxn6nu1UYnNJWFGShPLa3frrjI8.ttf') format('truetype'), /* Safari, Android, iOS */
       url('//fonts.gstatic.com/l/font?kit=ZvcMqxEwPfh2qDWBPxn6nt2FN73HCFuf_TNIxcXiPSI&skey=c2b76fd8ebf2629b&v=v13#Merriweather') format('svg'); /* Legacy iOS */
}
...

so CSS code could be selected and used right away without the need to download archive.

Do not do this; the fonts.gstatic.com URLs are not guaranteed stable. Only use the CSS API.

As @davelab6 said, I've currently no intention in doing this, especially since it cannot be considered to be stable.
