language-server: similar to function, the keywords for class, interface, var, and const are included in hover

Also, get and set for accessors. Other keywords, like dynamic, final, extends, and implements are excluded. TypeScript does function and class for sure, but not the others. It seems safe to include interface, var, and const in AS3, though.
