TS6133 error when "noUnusedLocals": true

[davyvanlaere]

When including version 1.3.0 in a project where "noUnusedLocals" in the tsconfig file is set to true:

ERROR in node_modules/angular2-lightbox/src/lightbox-overlay.component.ts(27,11): error TS6133: '_classList' is declared but its value is never read.

My suggestion:

• use @HostBinding('class') on the _classList field.
• remove it from the 'host' section of the @Component annotation
