return fn() or default value (in case of exception)

# tryor.js
Give it a function and a default value. `tryor` will give you back the return value of
the function or, in case the function threw an exception, the default value.
Works in node and browsers.



## Usage
```javascript
    // do this
    var config = tryor(function() {
        return JSON.parse(userProvidedConfigString);
    }, {});

    // instead of
    var config; // or var config = {}; and empty catch
    try {
        config = JSON.parse(userProvidedConfigString);
    } catch (e) {
        config = {};
    }
```

Works extra well with ES6-style `const` variables.
