Updated Atom syntax

[valeriecodes]

I was getting a warning in atom for deprecated syntax (pasted below):

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 .gutter, :host .gutter => atom-text-editor .gutter,atom-text-editor .gutter
• atom-text-editor .gutter .line-number.cursor-line, :host .gutter .line-number.cursor-line => atom-text-editor .gutter .line-number.cursor-line,atom-text-editor .gutter .line-number.cursor-line
• atom-text-editor .gutter .line-number.cursor-line-no-selection, :host .gutter .line-number.cursor-line-no-selection => atom-text-editor .gutter .line-number.cursor-line-no-selection,atom-text-editor .gutter .line-number.cursor-line-no-selection
• atom-text-editor .wrap-guide, :host .wrap-guide => atom-text-editor .wrap-guide,atom-text-editor .wrap-guide
• atom-text-editor .indent-guide, :host .indent-guide => atom-text-editor .indent-guide,atom-text-editor .indent-guide
• atom-text-editor .invisible-character, :host .invisible-character => atom-text-editor .invisible-character,atom-text-editor .invisible-character
• 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.is-focused .cursor, :host(.is-focused) .cursor => atom-text-editor.is-focused .cursor,atom-text-editor .cursor
• atom-text-editor.is-focused .selection .region, :host(.is-focused) .selection .region => atom-text-editor.is-focused .selection .region,atom-text-editor .selection .region
• atom-text-editor.is-focused .line-number.cursor-line-no-selection, atom-text-editor.is-focused .line.cursor-line, :host(.is-focused) .line-number.cursor-line-no-selection, :host(.is-focused) .line.cursor-line => atom-text-editor.is-focused .line-number.cursor-line-no-selection, atom-text-editor.is-focused .line.cursor-line,atom-text-editor .line-number.cursor-line-no-selection,atom-text-editor .line.cursor-line
• .comment => .syntax--comment
• .string => .syntax--string
• .constant.numeric => .syntax--constant.syntax--numeric
• .constant.language => .syntax--constant.syntax--language
• .constant.character, .constant.other => .syntax--constant.syntax--character, .syntax--constant.syntax--other
• .keyword => .syntax--keyword
• .storage => .syntax--storage
• .storage.type => .syntax--storage.syntax--type
• .entity.name.class => .syntax--entity.syntax--name.syntax--class
• .entity.other.inherited-class => .syntax--entity.syntax--other.syntax--inherited-class
• .entity.name.function => .syntax--entity.syntax--name.syntax--function
• .variable.parameter => .syntax--variable.syntax--parameter
• .entity.name.tag => .syntax--entity.syntax--name.syntax--tag
• .entity.other.attribute-name => .syntax--entity.syntax--other.syntax--attribute-name

• .invalid => .syntax--invalid
• .invalid.deprecated => .syntax--invalid.syntax--deprecated
  Automatic translation of selectors will be removed in a few release cycles to minimize startup time. Please, make sure to upgrade the above selectors as soon as possible.

I think I've made all the specified updates.
