Deprecated selector in `monokai-slate\index.less`

[ferux]

In monokai-slate\index.less:

Starting from Atom v1.13.0, the contents of atom-text-editor elements are no longer encapsulated within a shadow DOM boundary. This means you should stop using :host and ::shadow pseudo-selectors, and prepend all your syntax selectors with syntax--. To prevent breakage with existing style sheets, Atom will automatically upgrade the following selectors:

• atom-text-editor, :host => atom-text-editor,atom-text-editor

• atom-text-editor .invisible-character, :host .invisible-character => atom-text-editor .invisible-character,atom-text-editor .invisible-character

• atom-text-editor .indent-guide, :host .indent-guide => atom-text-editor .indent-guide,atom-text-editor .indent-guide

• atom-text-editor .wrap-guide, :host .wrap-guide => atom-text-editor .wrap-guide,atom-text-editor .wrap-guide

• atom-text-editor .gutter, :host .gutter => atom-text-editor .gutter,atom-text-editor .gutter

• atom-text-editor .gutter .cursor-line, :host .gutter .cursor-line => atom-text-editor .gutter .cursor-line,atom-text-editor .gutter .cursor-line

• atom-text-editor .line-number.cursor-line-no-selection, :host .line-number.cursor-line-no-selection => atom-text-editor .line-number.cursor-line-no-selection,atom-text-editor .line-number.cursor-line-no-selection

• atom-text-editor .invisible, :host .invisible => atom-text-editor .invisible,atom-text-editor .invisible

• atom-text-editor .cursor, :host .cursor => atom-text-editor .cursor,atom-text-editor .cursor

• atom-text-editor .selection .region, :host .selection .region => atom-text-editor .selection .region,atom-text-editor .selection .region

• atom-text-editor .search-results .marker .region, :host .search-results .marker .region => atom-text-editor .search-results .syntax--marker .region,atom-text-editor .search-results .syntax--marker .region

• atom-text-editor .search-results .marker.current-result .region, :host .search-results .marker.current-result .region => atom-text-editor .search-results .syntax--marker.current-result .region,atom-text-editor .search-results .syntax--marker.current-result .region

• atom-text-editor .gfm, :host .gfm => atom-text-editor .syntax--gfm,atom-text-editor .syntax--gfm
