Cătălin Mariș cdade05315 fix: use only one 180x180px touch icon (#1213) ...

* Include just one 180x180px touch icon`.

  Over time as Apple released different size displays for their
  devices, the requirements¹ for the size of the touch icon have
  changed quite a bit:

   * 57×57px – iPhone with @1x display and iPod Touch
   * 72×72px – iPad and iPad mini with @1x display running iOS ≤ 6
   * 76×76px – iPad and iPad mini with @1x display running iOS ≥ 7
   * 114×114px – iPhone with @2x display running iOS ≤ 6
   * 120×120px – iPhone with @2x and @3x display running iOS ≥ 7
   * 144×144px – iPad and iPad mini with @2x display running iOS ≤ 6
   * 152×152px – iPad and iPad mini with @2x display running iOS 7
   * 180×180px – iPad and iPad mini with @2x display running iOS 8+

  However, most iOS users will be on the latest 2 versions² of iOS
  and using newer devices, so nowadays, one 180x180px touch icon is
  enough.

  Also, if needed, the icon will be automatically³ downscaled by
  Safari, and the result of the scaling is generally ok.

* Remove unneeded `sizes` attribute.

  When using only one touch icon there is no need to use the `sizes`
  attribute.
