Align SVG markup across Foundation products by:
- unifying XML declaration,
- removing unnecessary `standalone="no"` attribute as it's default,
- removing unnecessary `enable-background` attribute as it got removed
from standard
- removing all SVG editor metadata
- adding `width` and `height` attributes where missing,
- removing all `g` group elements except where necessary for transforms,
- putting attributes on `path`,
- removing unnecessary ids and
- unifying whitespace.
Also
- changing 'expand' and 'gear' icon colors to resemble general button style,
- while at this renaming 'gear_gray' to 'gear' including CSS reference,
- slightly adapt remaining colors to WikimediaUI color palette and
- deleting unused, unreferenced icon files.
Saving up to 79% file size before gzipping.

Aligning to WikimediaUI style guide by replacing colors with
standard color palette equivalents, merging close colors
(ex: `#E6E6E6` & `#eee` become `#eaecf0` ) and slightly increase
contrast on a few to meet WCAG 2.0 level AA criteria.
Also:
- following other code bases like MobileFrontend or OOjs UI in
using `border-radius` property instead of obsolete mixin
- removing non-existing browser vendor prefixes in mixins
- removing non-used Less variables
- bringing CSS/Less code closer to coding standards and
- simplifying Less code where applicable

Replacing colors with ones from current WCAG 2.0 level AA compliant
color palette. Also improving SVG files by svgo optimization where
easily applicable and cleaning up some minor Less shortcomings.
