[Feature Request]: Show const hints for strings

[Shtoyan]

const hints show values for core classes, but not for your custom, extended ones

Please add hint value for string type consts (and maybe for class's and others too?).

const STRING_CONST="TEXT!";

function ConstTest() {
    log(Pi);            // vscode hint shows value for computed types
    log(STRING_CONST);  // not for a string tho :c
}

Technically the extension will only display the computed value of a const field. i.e. primitive types such as int, float, bool etc.

Oh god, I didn't check other types, I feel stupid. Yeah would be nice to have that enhancement.

I fixed the description and title, feel free to change further.
