@blueprintjs/tslint-config@1.2.0

  • Also added blueprint-icon-components rule to enforce JSX component or string literal usage for icon props. This rule is disabled by default and has little practical purpose until we ship individual components for the icons #2193
• removed file-header configuration as it mentioned Palantir
